Sorry, I can't answer name of debian pthread-devel package but I think you
also have some sort of configure error.  I don't see the "-lpthread" during
the link.  Can you reverify that you did the following line?

export LIBS="-lpthread"

If that doesn't work then try adding this after the "make distclean" step
but before configure step:

export PTHREAD_LIBS="-lpthread"

Nicolas,  I'm curious why you didn't recommend the following instead:

make distclean
./configure --enable-pthread

Does that not work correctly under debian with git?  Anything I can do to
help get that working?

Perhaps it was just some past confusion in debian from having to use
"--disable-fork" to get pthread working and that not being obvious?
