Question on Tru64unix and building a Python-2 environment

Hello,

Is anyone running Python version 2.5.<something> (or higher) on Tru64? 
If so, were you able to build it from the source distribution? I have
been trying to build Python-2.5.6, both with the native Tru64 C compiler
and with gcc-4.6.3, but I keep running into problems in the extensions
build section. Specifically: the native Tru64 C compiler appears to build
cleanly; however, the 'make test' fails on the test_ctypes, test_file and
test_zlib steps. I suspect that the test_zlib failure can be addreseed, but
the test_ctypes and test_file failures may be more significant problems;
the gcc build fails on the _curses and _curses_panel steps identified by
the gcc compiler as a problem with the curses.h/ncurses.h headers(?). I
have built other software with this gcc-4.6.3 environment without running
into that particular issue.
I would appreciate any suggestions or references for further work to
resolve the issues that I have encountered.

Thanks,
Bill
