Problem with PHP3.0.17 and imap+krb5.

Hello, I'm trying to install PHP 3.0.17 in a RH 6.2 box with IMAP 4.7-5 compiled to support Kerberos. The version 3.0.16 had a configuration option --with-kerberos which solved this problem: Starting httpd: Syntax error on line 249 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib/apache/libphp3.so into server: /usr/lib/apache/libphp3.so: undefined symbol: gss_mech_krb5 However, in version 3.0.17 this option doesn't work. What can I do? =( My configuration is this: ./configure \ --with-apxs \ --enable-versioning \ --with-imap \ --with-ftp \ --with-gd \ --with-jpeg-dir \ --with-ttf \ --with-gettext \ --with-x \ --with-mysql \ --with-pgsql \ --with-ldap \ --with-openssl \ --with-xml \ --with-exec-dir \ --enable-track-vars \ --enable-force-cgi-redirect \ --enable-discard-path \ --with-kerberos \ --with-dmalloc Thank you. Rodolfo.
