Alright -- having a bad couple days here compiling Apache 2.2.21 on CentOS 5.7 with the following configure commands:
./configure --enable-ssl=shared --with-ssl=/usr/local/openssl
I've compiled from source OpenSSL 1.0.0e from source:
./config --prefix=/usr/local --openssldir=/usr/local/openssl shared zlib-dynamic
I attempt to start Apache and it returns:
httpd: Syntax error on line 54 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/mod_ssl.so into server: /usr/local/apache2/modules/mod_ssl.so: undefined symbol: SSL_get_servername
If I look at how the libraries are linked, this is what I get:
[root@web1 modules]# ldd mod_ssl.so

Basically, I've tired compiling from source OpenSSL (both 0.9.8r and 1e), having yum reinstall from the repos, done a make clean and remade both OpenSSL and Apache numerous times -- but I can't get it to compile into the apache base or dynamically as a shared object file.
What am I doing wrong here?
Update 1:
After doing a make clean and make distclean, I've reconfigured with the same parameters as above without any effect.
The config.log is at Pastebin.
Update 2:
Modifying the LD_LIBRARY_PATH had no effect on the lib-deps of mod_ssl.so.
UPDATE 3:
I've compiled and recompiled many times, and verified with ldconfig that the OpenSSL libs dir is in my path, and included in ld.so.conf. Still cannot get httpd/mod_ssl to load the library at runtime.
