Look into the Inline module from CPAN and possibly bundled with new
Perls. It's neat:

With Inline.pm you'll need to do none of these yourself. You just put
the C source inline in your Perl script, and the module takes care of
compilation (and caching the resultant object for the next time),
(run-time) linking, and binding.
There are some issues--there are always some issues--for example in
packaging this for execution where there's no compiler, or doing the
connections if your C source needs preprocessing. But tell me this isn't
a nice start :-)
