tqisjim has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to upgrade my system to Perl 5.16. I'm having trouble as indicated. So far, based on some Google searches, I've concluded the problem does not seem specific to XML::Parser::Expat. Otherwise, there doesn't seem to be a definitive solution posted anywhere. Does anybody know where this symbol originates?
# Error: Can't load '/home/jim/perl5/lib/perl5/i686-linux-gnu-thr +ead-multi-64int/auto/XML/Parser/Expat/Expat.so' for module XML::Parse +r::Expat: /home/jim/perl5/lib/perl5/i686-linux-gnu-thread-multi-64int +/auto/XML/Parser/Expat/Expat.so: undefined symbol: PL_thr_key at /usr +/local/lib/perl5/5.16.2/i686-linux/DynaLoader.pm line 190.
Thanks!
