lang/python21 problem

[Justin C. Sherrill]

I've been having the bulk build of pkgsrc packages freeze up on the
lang/python21 build; it just sits forever on the config step:

checking if PTHREAD_SCOPE_SYSTEM is supported...

I've filed a PR for pkgsrc with this.  However, the python21 package
hasn't changed since 2006, and this package built fine on 1.10, which
makes me wonder if it's something that crept into the most recent release.

Full text of build below, for the curious:
pkgbox# bmake
=> Bootstrap dependency digest>=20010302: found digest-20070803
=> Bootstrap dependency checkperms>=1.1: found checkperms-1.10
=> Checksum SHA1 OK for Python-2.1.3.tgz
=> Checksum RMD160 OK for Python-2.1.3.tgz
===> Installing dependencies for python21-2.1.3nb15
==========================================================================
The following variables will affect the build process of this package,
python21-2.1.3nb15.  Their current value is shown below:

        * BDB185_DEFAULT = db1
        * BDB_DEFAULT = db4

Based on these variables, the following variables have been set:

        * BDBBASE = /usr
        * BDB_LIBS (defined, but empty)
        * BDB_TYPE = db1

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/pkg/bin/bmake clean' after
the changes.
