There's also a have_library() method within, eg,
http://search.cpan.org/src/PHISH/XML-LibXML-Common-0.13/Makefile.PL
which might be considered for ExtUtils::CBuilder. Although
more complicated than the above, this tests if some xs
glue can be built with $foo, and so can catch some
perl-specific problems. It also has some necessary tweaks to
work on Win32.
