Sounds great.

This is a problem since MakeMaker makes no provision for using 
uninstalled libraries.  The only way it works reliably is if the 
libraries are installed.  Regardless, I have found ways to use 
uninstalled libraries if the Perl extension is built as static 
(stand-alone executable).  There is an annoying issue is that when 
Makefile.PL is 'executed' to create Makefile, the libraries are 
scanned for at that time.

Don't expect it to be pretty.  Everything is implemented using 
Automake hooks.  For a shared build, the extension is not built until 
'make install' time since the module extension will fail if the 
libraries are not already install.
