Not quite. It should be possible to build any extension statically linked to
Perl. (Not using Inline. I suspect you can't do this with Inline, but you
can with regular XS extensions)
Assuming the Makefile is generated by Makefile.PL, then
make perl
should generate a new perl executable staticly linked to that extension
(and all existing staticly linked extensions)
But it seems that if you're using a vendor supplied perl that was built with
a shared libperl.so, then this isn't going to work*. You'll need to compile
your own perl. The default in the source tarball is not to have a shared
libperl.so; it just seems that most vendors choose to override this setting.
