in thread undefined symbol: PL_thr_key
I'll not disregard your question, for the sake of future readers.
The error comes from a module compiled against threaded Perl while your Perl installation is not threaded (probably because you recompiled it). The solution is to recompile the module against the new Perl.
(I had a few such problems when toggling the threads flag on Gentoo.)
