[Zope] FreeBSD compile error 2.4.x to 2.4.3

[Gary & Karyn]

I'm getting the following error trying to compile Zope 2.4.x to 2.4.3
upgrade on FreeBSD

Compiling extensions in lib/python
cp /usr/local/lib/python2.1/config/Makefile.pre.in .
cp: /usr/local/lib/python2.1/config/Makefile.pre.in: No such file or
directory
Traceback (most recent call last):
  File "/usr/local/zope/2.4.2/w_pcgi.py", line 111, in ?
    if __name__=='__main__': main(sys.argv[0])
  File "/usr/local/zope/2.4.2/w_pcgi.py", line 109, in main
    import wo_pcgi; wo_pcgi.main(me)
  File "/usr/local/zope/2.4.2/wo_pcgi.py", line 105, in main
    import build_extensions
  File "/usr/local/zope/2.4.2/inst/build_extensions.py", line 102, in ?
    make('lib','python')
  File "/usr/local/zope/2.4.2/inst/do.py", line 133, in make
    do("cp %s ." % wheres_Makefile_pre_in())
  File "/usr/local/zope/2.4.2/inst/do.py", line 104, in do
    if i and picky: raise SystemError, i
SystemError: 256

the python2.1 is a python that worked just fine for 2.4.2...However, unless
I am being incredibly stupid, it doesn't have a config folder:
Makefile.pre.in is in the top python2.1 folder.  Has anyone else encountered
this, or feel the need to fix it?  If not, I guess I'll dig in a bit...look
at "wheres_Makefile_pre_in", for instance...

Thanks
