The automatic building of plpython is not enabled yet. From
src/pl/Makefile, we have:

# Doesn't build portably yet.
#ifeq ($(with_python), yes)
#DIRS += plpython
#endif

Hence, you will have to cd to src/pl/plpython and run make manually.

Did you forget to apply my patch? I have only submitted it to
pgsql-patches, it has not been accepted into CVS. Without my patch you
would get errors like the above. With my patch, plpython should build
OOTB -- you should not have to do unrecommended things like #3 above.
