Ok, making some progress.  Still:

thread.o(.text+0xb3): undefined reference to `pthread_sigmask'
thread.o(.text+0xd9): undefined reference to `pthread_create'
thread.o(.text+0xf3): undefined reference to `pthread_sigmask'
thread.o(.text+0x12a): undefined reference to `pthread_detach'
/usr/lib/python2.2/config/libpython2.2.a(posixmodule.o): In function

/usr/lib/python2.2/config/libpython2.2.a(posixmodule.o): In function 
posixmodule.o(.text+0x188f): undefined reference to `forkpty'

So another -lXXX is needed.  Any hints?  By the way, this stuff feels way more 
hackish than it should.  Is it documented anywhere?  I pored over the standard 
docs, but couldn't find any specific examples.

Sorry, but you're venturing into fully uncharted territory here.  So there may 
be monsters behind the trees :)  But please report back when you return, as 
I'm sure the experience will be of use to others.  Also, comp.lang.py might be 
of assistance on this, since there are quite a few folks there with embedding
