RC2 make error on Sybase

I'm trying to compile with the following options: ./configure --with-xml --with-pgsql --with-mysql --with-sybase --with-apxs=/usr/sbin/apxs --enable-track-vars I get this when I do 'make install': make[2]: Entering directory `/usr/src/php-4.0RC2/ext/sybase' make[3]: Entering directory `/usr/src/php-4.0RC2/ext/sybase' /bin/sh /usr/src/php-4.0RC2/libtool --silent --mode=compile gcc -DHAVE_CONFIG_H -I. -I/usr/src/php-4.0RC2/ext/sybase -I/usr/src/php-4.0RC2 -I/usr/include/apache/ -I/usr/src/php-4.0RC2/Zend -I/usr/src/php-4.0RC2 -I/usr/src/php-4.0RC2/ext/mysql/libmysql -I/home/sybase/include -I/usr/src/php-4.0RC2/ext/xml/expat/xmltok -I/usr/src/php-4.0RC2/ext/xml/expat/xmlparse -DEAPI=1 -DXML_BYTE_ORDER=12 -g -O2 -Wall -c sybase.c In file included from sybase.c:27: php_sybase.h:83: sybfront.h: No such file or directory php_sybase.h:84: sybdb.h: No such file or directory php_sybase.h:85: syberror.h: No such file or directory sybase.h:34: sybfront.h: No such file or directory sybase.h:35: sybdb.h: No such file or directory sybase.h:36: syberror.h: No such file or directory make[3]: *** [sybase.lo] Error 1 make[3]: Leaving directory `/usr/src/php-4.0RC2/ext/sybase' make[2]: *** [install-recursive] Error 1 make[2]: Leaving directory `/usr/src/php-4.0RC2/ext/sybase' make[1]: *** [install-recursive] Error 1 make[1]: Leaving directory `/usr/src/php-4.0RC2/ext' make: *** [install-recursive] Error 1 This is on Mandrake 7.0, MySQL 3.22.32 (RPMs), PGSQL 7.0 (RPMs), Sybase 11.9.2, and Apache 1.3.9. I installed all of the Sybase RPMs (not knowing what I'd need), ie: sybase-common-11.9.2-1.i386.rpm sybase-doc-11.9.2-1.i386.rpm sybase-monserver-11.9.2-1.i386.rpm sybase-openclient-11.1.1-1.i386.rpm sybase-sqlremote-6.0.2-1.i386.rpm sybase-ase-11.9.2-1.i386.rpm Any suggestions?
