I saw similar behaviour (a library which needs pthread does not work
with FreeBSD's unthreaded perl) in other perl modules, too. The patch
below seems to fix the problem for FreeBSD, at least "make test" does
not fail anymore. I suspect that netbsd and openbsd also need this
patch.
Another note: some files in the distribution are not listed in the
MANIFEST. Which means that makefile rules like "make dist" or
"make disttest" do not work. "make dist" is the preferred way
to create a distribution tarball.
