I think this must be breakage in your local python installation, not in
Postgres. Note the complaint is that /usr/include/python2.3/pyconfig.h
disagrees with /usr/include/features.h ... it's not hard to decide who's
at fault there. PG could be an accessory to the crime, but AFAICS we've
not mucked with include order or predefined symbols for plpython.c
lately; so if we broke it, it was awhile ago.

This is surely not a "must fix tomorrow" issue, but please look into it
when you get back from your road trip.

(Where are you going, anyway? 3600 miles is a long way...)

regards, tom lane
