Python-2.2.1, Solaris7, make test fails...

[Hugh Sasse Staff Elec Eng]

Trying to bring python up to date (working version is 1.5.2) on a
Sun Sparc Solaris2.7 system:

GNU Make version 3.79, by Richard Stallman and Roland McGrath.
Built for sparc-sun-solaris2.7

gcc --version  ==  2.95.3

Doing `gmake test` in the Python-2.2.1 directory gives:
        [...]
running build_scripts
not copying /home/hgs/Python-2.2.1/Tools/scripts/pydoc (up-to-date)
find ./Lib -name '*.py[co]' -print | xargs rm -f
./python -E -tt ./Lib/test/regrtest.py -l

Could someone suggest how to proceed, please?
        Thank you,
