I downloaded the 3.0 tarfile and did a straightforward

    configure
    make
    make test

on Solaris 10 and got several test failures:

    290 tests OK.
    4 tests failed:
        test_cmath test_math test_posix test_subprocess

Here's the output for just the failing tests:

    test test_cmath failed -- Traceback (most recent call last):

    AssertionError: OverflowError not raised in test exp0052: exp(complex(710.0,

Here's the test_math output run through regrtest with the -v option:
