Mysql + PHP4 problem

Greetings, I'll appreciate any help on this: PHP is installed and working, but refuses to acknowledge mysql. Mysql. on the other hand, is working OK too (for Bugzilla). Details: Mandrake 8; PHP 4.0.6 (but reports 4.0.4pl1 on php -v) ; mysql 3.23.39 PHP was built with --with-mysql=/usr/local/mysql --with-apxs php -h gives out a warning: unable to load dynamic library '/usr/lib/php/extensions/mysql.so' .... file not found. (not that it really matters, but: httpd -l lists mod_so.c) Now - I've tried to link the only mysql.so file in the system (/usr/local/lib/perl5/site_perl/5.6.1/i686-linux/auto/DBD/mysql/..) to that location (though the location seems strange), but then failed on undefined refs in that library. Thanks in advance Ronen rfriedman@regisoft.com
