smart 0.50 requires python >= 2.4? (smart/ccache.so: undefined symbol: Py_VISIT)

Correct.  I've fixed a leak in the C code after rc1 was out, and
that's why it went in for 0.50 instead of postponing it to the
next release.  The fix was interesting enough that releasing 0.51
shortly after to solve some major issue would be a better choice.
