I dug into this. The breakage was recorded by buildhistory:

And look at that, an openssl patch in between those dates:

==========================================================================
From 01ea85f7f6c53c66c76d6f832518b28bf06ec072 Mon Sep 17 00:00:00 2001
From: Andrei Gherzan <andrei at gherzan.ro>
Date: Tue, 21 Feb 2012 23:03:55 +0000
Subject: openssl: Move libcrypto to base_libdir

This fix is for dhclient. It needs libcrypto at runtime and if
libcrypto is in libdir, it's path can be inaccessible on systems
where /usr is on nfs for example or dhclient is needed before
/usr is mounted.

Signed-off-by: Andrei Gherzan <andrei at gherzan.ro>
==========================================================================

I'm going to band-aid it so we can get a working python hashlib module in the 'denzil' branch, hopefully someone will come up with a proper fix soon.

regards,

Koen
