nm /lib/libssl.so | grep OPENSSL_add_all_algorithms_noconf
'nm' shows the symbolic names in an archive or library file, and 'grep' finds the symbol
you want (assuming it's there...)

I was looking at the install instructions for openssl-0.9.7d and it said that after running ./configure, and then make, that some *.a files are installed in /usr/local/ssl/lib, not *.so files. Also, It seems that when I build openssl-0.9.7d, it seems to show that /lib/libssl.so* was modified. Is there a way for me to check /lib/libssl.so* to see if it contains OPENSSL_add_all_algorithms_noconf or not?

I have a question about your reponse:______________________________________________________________________
If php is finding /usr/local/ssl/include/evp.h but using
/lib/libssl.so instead of /usr/local/ssl/lib/libssl.so, how do I
link
php to the correct lib?
I thought about moving/renaming /lib/libssl.so, but since it seems to be linked to /lib/libssl.so.x.y.z, I am concerned that there may be other applications dependant on it, and I am not sure how to check what applications are using this file.
I suppose there may be an additional directive that I can pass to php in ./configure that defines the location of the correct libssl.so file to use.

OK, a few points:on
The way you configured OpenSSL, the library files ended up in
/usr/local/ssl/lib. Also, they are named libcrypto.so.x.y.zt and
libssl.so.x.y.zt with the symbolic links libcrypto.so.0 and
libssl.so.0 (note, ending with 0, not 2) as well as libcrypto.so
and
libssl.so. This I know for sure. If PHP was linked with
/lib/libssl.so.2, it did not link with the libssl.so that you
imagine. Actually, the ending .2 makes me think you're running
onRedHat or a derivate thereof, since they use that major library version.
The symbol OPENSSL_add_all_algorithms_noconf exists in OpenSSL 0.9.7x but not in 0.9.6x.
What I imagine happened is that PHP configuration specified correctly where to find OpenSSL header files (and therefore got /usr/local/ssl/include/openssl/evp.h) but not where to find the files to link with (and therefore hit /lib/libssl.so instead of /usr/local/ssl/lib/libssl.so).
