Thanks Max.  Those were good write ups.  I'm pleased to report that I've got 
GHC hooked into Perl as a shared library (i.e., can call my GHC code from 
Perl).  I'm  working on trying to get a reasonable build system solution now.

So far I've been trying to build a single shared library, but I thinking the 
easiest/intended way might be to just get GHC to just build its own library 
and then specify it as a required shared library to the Perl stub library.

This way I wouldn't have to mix flags from the build systems in the final link.

(although a shared library of stubs to a shared library seems a bit strange)

Cheers!  -Tyson

PS:  Thanks to everyone responsible for getting shared libraries working.
