Thanks, Chad, for the nudge.

This server is running a core based on RH 6.2, although it is by no means a
default install. It has been rather massaged. Linux kernel is 2.4.19.

That sounds interesting. Maybe next time I try the install routine, I will
run it with the *shared* option, as less disk and memory space is
definitely appealing to me.

Machine is Intel based. PIII, I believe.

glibc-2.1.3, or to be more precise:
 RedHat version 2.1.3-28

I've posted my latest version of the /Modules/Setup file here:
http://mathxy.com/Setup.txt

With the /Modules/Setup file shown above, I got the following make test
results:

174 tests OK.
1 test failed:
    test_largefile
18 tests skipped:
    test_al test_cd test_cl test_curses test_dl test_email_codecs
    test_gl test_imgfile test_linuxaudiodev test_minidom test_nis
    test_pyexpat test_sax test_socket_ssl test_socketserver
    test_sunaudiodev test_winreg test_winsound
4 skips unexpected on linux2:
    test_minidom test_linuxaudiodev test_pyexpat test_sax
make: *** [test] Error 1


I don't care about the linuxaudiodev file, but I would like to get the
largefile test and the XML type of libraries to work. :/

Also, I would like to get sockets working with SSL support.

Earlier, I tried the following in the /Modules/Setup file:

# for socket(2), without SSL support.
#_socket socketmodule.c

# Socket module compiled with SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_socket socketmodule.c \
	-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
	-L$(SSL)/lib -lssl -lcrypto

But the above wouldn't work (gave horrible error messages and wouldn't even
produce a python executable. It really is a puzzlement, too, because we do
have the files and directories referenced on the machine (i.e.
/usr/local/ssl exists, as does /usr/local/ssl/include and
/usr/local/ssl/include/openssl and /usr/local/ssl/lib )

When I execute the version command for openssl I get this response from the
server:
OpenSSL 0.9.6e [engine] 30 Jul 2002


Any suggestions, ideas or tips would be much appreciated.
