[Antoine Pitrou]

New submission from Antoine Pitrou:

Building from a fresh checkout with "./configure" followed by "make -j4" fails here:

$ make -j4
[... snip ...]
./python -E -S -m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
	echo "generate-posix-vars failed" ; \
	rm -f ./pybuilddir.txt ; \
	exit 1 ; \
fi

Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
