I am trying to enable CURL in php, and possibly update php as well. I have run into a road block where Apache seems to be running the wrong version of PHP. Here is some evidence.

#lsof | grep php
httpd     18397    nobody  135w      REG        8,3       242     528537 /usr/local/apache/modules/libphp5.so

I download the latest php 5.2.13 and build from source. I run a service httpd stop, do a make install and then I manually overwrite /usr/local/apache/modules/libphp5.so just to be safe. Using ldd i can see that its my fresh binary compiled with curl (the old one doesn't have curl.)

ldd /usr/local/apache/modules/libphp5.so | grep curl libcurl.so.4 => /usr/local/lib/libcurl.so.4 (0x0064e000)

I execute a phpinfo() and 5.2.3 is being executed instated of my new 5.2.13 and "curl" is nowhere to be found. What am I doing wrong? Why is curl disabled even though its statically linked? This is a RHEL 5.5 system.
