[yocto] undefined reference to `pthread_getspecific' in perl-native_5.12.2.bb task do_compile?

Wed Jun 8 11:19:58 PDT 2011

This email (on the gumstix mailing list) describes the problem:
http://sourceforge.net/mailarchive/message.php?msg_id=27373548.  libc
has moved in Ubuntu 11.04.

Later in that thread is a link to this OE patch:
http://patches.openembedded.org/patch/1659/.  Since I'm a Yocto and OE
newbie, it's not clear to me if this patch can be applied to Yocto
Project 1.0.1, and if so, how.

I might be better off installing 10.10 on my machine.  (It's new, so I
don't need to worry about backing up and restoring any files.)  But
then I may be missing out on a learning opportunity and a chance to
help out the community.

Would someone be able to walk me through applying or adapting this
patch to Yocto?
