Hey there again,

	Hope you don't mind, but I'm going (to attempt) to reply to the second
message in this thread. A few things that are going on that might be
interfering with how your tests are being run...

	(Don't quote me specifically on this, I'm not a portage internals
person - or even happy when I have to look at the python that is
portage...) When you are running the tests via portage, your working in
a different environment than when your testing via the command line.
First and foremost there's the sandbox to consider, which among other
things would be trumping your local environment (including the
definition of $HOME) and using a sanitized, pseudo-chroot (best I can
think of to describe it) env. Also, when portage is running the tests,
it is my thinking it will always return to your shell a 0 status -
because at that point, portage is cleanly exiting. Now on the inside,
its getting the die status, wrapping it in 'our' standard message about
where to file bugs, etc., and printing it all out stdout.
	The lack of a defined useshrplib makes sense - in the case of the
current (ie, not what I've been playing around with in my experimental
overlay, where I wreak complete havoc on the gentoo perl world) ebuilds
for perl, libperl is built separately, and perl itself is built against
a static libperl.a (the libperl.so is around for everything else in the
known universe), so I wouldn't put any stock into that missing def.
	So (hopfully beating the next question to the punch) how best to test
in this case? I'd probably do a manual
	ebuild package compile
	cd /var/tmp/portage/<package>/work/<working dir>
	make test
	which *should* at least yield whether everything is working ok.
Alternatively (painfully) you can install the package, then unpack the
source somewhere and make test there (so its using your live system's
install of the module against the test harness suite in the unpack).
	And as a final note...this is one of the reasons tests are enabled
universally ;) Hopefully all of that made sense (my coffee just finished
brewing if that gives any indication on the state of my consciousness),
but if not, lemme know, hopefully someone more cognizant and intelligent
will jump in to correct me.
