Do you recall if Math::Pari had difficulties when tested and installed? Has ldconfig been run?

I get:

$ perl -MMath::Pari -e 'print $Math::Pari::VERSION,$/'
2.010201
$ # installing Crypt::Random from CPAN
...
PERL_DL_NONLAZY=1 /usr/bin/perl -Iblib/arch -Iblib/lib -I/usr/lib/perl
+5/5.6.0/i486-linux-thread -I/usr/lib/perl5/5.6.0 -e 'use Test::Harnes
+s qw(&runtests $verbose); $verbose=0; runtests @ARGV;' t/*.t
t/generator.........ok
t/makerandom_itv....ok
t/octet_string......ok
t/pari_misfeature...ok
t/random............ok
All tests successful.

$ $ perl -MCrypt::Random -e 'print $Crypt::Random::VERSION,$/'

Are you using a binary distribution of Math::Pari? You could have an ABI incompatable compiler.
