make distclean doesn't remove Modules/Setup anymore :) Also, I couldn't get
it to work with an old tree, even after several make distclean/reconfigures.
I got tired looking for it, so I just grabbed a new tree.

I have a couple of questions: what to do when setup.py doesn't work ? Is
there a way to make it bypass a module ? What about specifying include dirs
manually, for some modules (for instance, when you have readline source in a
separate directory, and want to link it statically.)

Here are are some specific squeals. See at the bottom for the most important
one :)

On BSDI, readline sits in /usr/local or /usr/contrib, and isn't detected by
setup.py. Also, SSL support for the socket module was not enabled, though
OpenSSL is installed, in the default path.

On Debian GNU/Linux' 'woody', the 'testing' (soon 'stable') branch, I can't
compile dbmmodule:

building 'dbm' extension
gcc -g -O2 -Wall -Wstrict-prototypes -fPIC -fpic -I. -I/home/thomas/python/python/dist/src/./Include -IInclude/ -c /home/thomas/python/python/dist/src/Modules/dbmmodule.c -o build/temp.linux-i686-2.1/dbmmodule.o
/home/thomas/python/python/dist/src/Modules/dbmmodule.c:24: #error "No ndbm.h available!"
error: command 'gcc' failed with exit status 1
make: *** [sharedmods] Error 1

(ndbm.h does exist, as /usr/include/db1/ndbm.h. There is also
/usr/include/gdbm-ndbm.h, but I'm not sure if that's the same.)

Nor can I build the _tkinter module there:

building '_tkinter' extension
gcc -g -O2 -Wall -Wstrict-prototypes -fPIC -fpic -DWITH_APPINIT=1 -I/usr/X11R6/include -I. -I/home/thomas/python/python/dist/src/./Include -IInclude/ -c /home/thomas/python/python/dist/src/Modules/_tkinter.c -o build/temp.linux-i686-2.1/_tkinter.o

In file included from /home/thomas/python/python/dist/src/Modules/_tkinter.c:45:/usr/include/tk.h:66: tcl.h: No such file or directory
error: command 'gcc' failed with exit status 1
make: *** [sharedmods] Error 1

The Tcl/Tk header files are stored in /usr/include/tcl<ver>/ on Debian,
which I personally like a lot, though it's probably a bitch to autodetect.
(I tried, using autoconf ;-P)

On Debian GNU/Linux 'sid', the current unstable branch, I can't compile
Python at all, now:

For the record, I don't have a /usr/lib/python2.1 directory on the other
machines either.

I haven't been able to test FreeBSD yet, will get to that later tonight.

And most importantly(!), on all these machines, 'make test' stops
functioning. In fact, after setup.py started building, you can't run 'make'
without 'make clean' anymore. You get a lot of undefined-symbol warnings
(see below.) If you run 'make clean;make test' it also doesn't work, because
the build directory is not in the Python library path, and regrtest.py
requires (at least) the time module.
