What is the output of ldd /usr/local/apache2/modules/mod_ssl.so? –  Zanchey Aug 18 '09 at 9:46

It turns out, its a problem with openssl, I got it to work with openssl-0.9.7m, most of the 0.9.8 releases did not work.As long as the LD_LIBRARY_PATH is set to something like LD_LIBRARY_PATH=usr/local/lib (because thats where libcryto and susch files are)

So when as long as openssl is working correctly, apache can mod_ssl can be used against 0.9.7m for mod_ssl. strange as there were many people with the same problem and no answer.

Many Thanks

What's in the ldconfig cache ? You can see it using ldconfig -p. Example :

ldconfig -p | egrep -i '(ssl|crypt)'

Be sure to have your openssl 0.9.8k build.

If not, update your /etc/ld.so.conf (or /etc/ld.so.conf/openssl.conf - I don't know how CentOS is organized). Then run ldconfig again, to update its cache.
