errors compiling ssh2 0.10

When I try to compile the latest (or version 0.9 for that matter), I get these errors. Can you please help me getting it compiled? /bin/sh /root/ssh2-0.10/libtool --mode=compile gcc -I. -I/root/ssh2-0.10-DPHP_ATOM_INC -I/root/ssh2- 0.10/include -I/root/ssh2-0.10/main -I/root/ssh2-0.10 -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/Zend -I/usr/include/php/TSRM -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -prefer-pic -c /root/ssh2- 0.10/ssh2.c -o ssh2.lo gcc -I. -I/root/ssh2-0.10 -DPHP_ATOM_INC -I/root/ssh2-0.10/include -I/root/ssh2-0.10/main -I/root/ssh2-0.10 -I/usr/include/php -I/usr/include/php/main -I/usr/include/php/Zend -I/usr/include/php/TSRM -I/usr/local/include -DHAVE_CONFIG_H -g -O2 -c /root/ssh2-0.10/ssh2.c -fPIC -DPIC -o ssh2.lo In file included from /usr/include/openssl/ssl.h:179, from /usr/include/php/main/php_network.h:78, from /root/ssh2-0.10/ssh2.c:26: /usr/include/openssl/kssl.h:72:18: krb5.h: No such file or directory In file included from /usr/include/openssl/ssl.h:179, from /usr/include/php/main/php_network.h:78, from /root/ssh2-0.10/ssh2.c:26: /usr/include/openssl/kssl.h:134: syntax error before "krb5_enctype" /usr/include/openssl/kssl.h:136: syntax error before '*' token /usr/include/openssl/kssl.h:137: syntax error before '}' token /usr/include/openssl/kssl.h:149: syntax error before "kssl_ctx_setstring" /usr/include/openssl/kssl.h:149: syntax error before '*' token /usr/include/openssl/kssl.h:150: syntax error before '*' token /usr/include/openssl/kssl.h:151: syntax error before '*' token /usr/include/openssl/kssl.h:151: syntax error before '*' token /usr/include/openssl/kssl.h:152: syntax error before '*' token /usr/include/openssl/kssl.h:153: syntax error before "kssl_ctx_setprinc" /usr/include/openssl/kssl.h:153: syntax error before '*' token /usr/include/openssl/kssl.h:155: syntax error before "kssl_cget_tkt" /usr/include/openssl/kssl.h:155: syntax error before '*' token /usr/include/openssl/kssl.h:157: syntax error before "kssl_sget_tkt" /usr/include/openssl/kssl.h:157: syntax error before '*' token /usr/include/openssl/kssl.h:159: syntax error before "kssl_ctx_setkey" /usr/include/openssl/kssl.h:159: syntax error before '*' token /usr/include/openssl/kssl.h:161: syntax error before "context" /usr/include/openssl/kssl.h:162: syntax error before "kssl_build_principal_2" /usr/include/openssl/kssl.h:162: syntax error before "context" /usr/include/openssl/kssl.h:165: syntax error before "kssl_validate_times" /usr/include/openssl/kssl.h:165: syntax error before "atime" /usr/include/openssl/kssl.h:167: syntax error before "kssl_check_authent" /usr/include/openssl/kssl.h:167: syntax error before '*' token /usr/include/openssl/kssl.h:169: syntax error before "enctype" In file included from /usr/include/php/main/php_network.h:78, from /root/ssh2-0.10/ssh2.c:26: /usr/include/openssl/ssl.h:909: syntax error before "KSSL_CTX" /usr/include/openssl/ssl.h:931: syntax error before '}' token /root/ssh2-0.10/ssh2.c: In function `zif_ssh2_methods_negotiated': /root/ssh2-0.10/ssh2.c:483: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:484: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:485: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:486: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:487: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:488: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:489: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:490: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:491: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c:492: warning: assignment discards qualifiers from pointer target type /root/ssh2-0.10/ssh2.c: In function `zif_ssh2_fingerprint': /root/ssh2-0.10/ssh2.c:536: warning: assignment discards qualifiers from pointer target type make: *** [ssh2.lo] Error 1
