apache+mysql+php4+redhat7

well, i've been trying to get php and mysql working on my fresh installation of red hat 7... i decided to compile everything i need. Got mysql working, apache working, php4 not working... following a tutorial from webmonkey, i installed php on apache as a dso(dynamic shared object)... everything went fine, but when trying to start the apache server i get the following error: Syntax error on line 205 of /usr/local/apache/conf/httpd.conf; Cannot load /usr/local/apache/libexec/libphp4.so into server: libmysqlclient.so. 10: cannot open shared object file: No such file or directory ./bin/apachectl start: httpd could not be started following a tip from the tutorial, i added /usr/local/apache/libexec to the /etc/ld.so.conf file... then i run ldconfig and reinstalled php4 with the same options i had before... unfortunately the result was the same!! i have no idea on how to solve the problem, if there is a libmysqlclient.so file somewhere, if this file's directory is the one to add to /etc/ld.so.conf instead of /usr/local/apache/libexec, but i certainly would apreciate some kind of help!! i've been reading the archive of this mailing list and found that many people have problems similar to this one, but with no answers, at list i didn't find any... so, if someone can help with something, thank you in advance!!
