You are trying to explicitly specify library files to be loaded on 
all ld invocations.  This is wrong.  Instead, you should specify a 
_path_ to load libraries from, much like you did with include 
directories.

Something like this should work for you:

./configure --with-cc-opt="-I/usr/local/ssl/include" \
            --with-ld-opt="-L/usr/local/ssl/lib"
