Forum OpenACS Q&A: Response to nsopenssl build problem
-Ldir: Add directory dir to the list of directories to be searched for `-l'.
-llibrary: Search the library named library when linking.

/etc/libdl.so library to give us the API for
the runtime linker, and adding the above
switches make that happen.
