Junk in, junk out.  This is a Perl module; if the Perl configuration
is busted bad enough, one is not able to build a Perl module, period.
Nothing specific to Math::Pari.  I do not think I *want* to treat this
case specially.

Some time I will ask you to run some tests, since I *am* testing the
headers...

BTW, any reason why ulong is *still* used in the sources?  I sent a
recipe how to fix it around 5 years ago.  IIRC, it was something as
simple as a global edit as in

  pfind src '=~ s/\bulong\b/PARI_ulong/'

followed by insertion of conditional `typedef PARI_ulong ulong;' (for
old extensions).  Maybe it is better still to change this to something more
specific, as in PARI_bigint_comp (waiting for a free-style C-like
declarations of PARI types).

Your perl is not correctly compiled.  Did you run `make test'?

Thanks.  Cannot find it in CHANGES, when was it made global?  It is
not in 2.0.15 yet...

This is typical for a configuration change without makeing realclean
(I'm adding this to README).  Underscore problem.  Please re-report.
