erlgtk config + new erl_interface = pthread-related errors?

[Chris Pressey]

Hi all,

I've successfully installed the erlang-r9c0,1 port on FreeBSD -STABLE,
and I'm trying to re-install erlgtk-0.9.6 on top of it.

But I'm seeing a new error in the configure stage that seems to have
something to do with the changes in erl_interface w.r.t. pthreads.  The
relevant output of 'make configure' follows:

yes

Any idea what could be causing this?  My hunch is it's something either
in the port or in my local configuration, rather than in the R9C dist
itself, but I guess it could be just about anything.  The pth-2.0.0 port
is installed, even though the erlang port doesn't seem to mention it
as a dependency.

TIA for any insight,
