With a little more work one could probably fall back to import from the
"dl" module in Python 2.4 (or, get the flag from the OS by writing a
three-line Cython module). It obviously also need to fail gracefully on
Windows if it doesn't already and so on.
David C. was -1 on inclusion in that thread, and noone spoke up in
support, and so I did not bother to spend time improving the patch. It
obviously need a little bit of polish before being submitted.

The patch is enabling a very generic mechanism and certainly won't stop
older MKL versions from working.
