more specifically, 'perl Makefile.PL' runs fine, 'make', runs fine, but 'make test' gives me quite a few errors. and being somewhat unaccustomed to linux, i was hoping someone could point me in the right direction. I'm running Debian, logged in as root, and when i run 'make test TEST_VERBOSE=1', this is what i get:

PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_h
