[Python-Dev] 2.3.3 test_pty sometimes fails on Solaris

I'm installing 2.3.3 on a Solaris 8 system. If I run "make test", it reports that test_pty failed and gives this error: test test_pty failed -- slave_fd is not a tty but if I run "./python Lib/test/test_pty.py" or ./python Lib/test/regrtest test_pty it seems the test succeeds. It smells sort of like the bug report at http://www.python.org/sf/864374. Any suggestions where I should look for culprits? I know zilch about ptys. Thx, Skip
