openssl has further external dependencies which must be available in
case you want to link to it statically.

Your config.log should contain more information. Without seeing that, I
guess that you are lacking the static version of libz.a the gzip
compression library.

I've added a patch to clarify the error message.

Just as Liam has already answered, LD_LIBRARY_PATH or /etc/ld.so.conf
should be of help here.

earlier /usr/local/lib was listed in the dynamic library search path by
default, recent distributions seem to have removed that.
