(I realize this is a "draft version", but ... )
This does not work on Linux.  It works only on
a Linux in which cc exists in the PATH and can
take a -shared argument to build a dso, etc.  To extend
this module beyond a 'draft' version that works on
a wide variety of platforms, you're going to wind
up with yet another libtool replacement.  Why
not just use libtool to begin with?
