Was this the same numpy 1.7.1 you used earlier, or a different setup?

64 bit Linux machine, Python 2.7.4 compiled from source (recently),
numpy freshly compiled from source today, making sure to remove
the old numpy installation fully between installs - note run in this order,
but I have tested some of these multiple times:

numpy 1.4.1 (built from source) succeeds.
numpy 1.5.1 (built from source) succeeds.
numpy 1.6.0 (built from source) fails.
numpy 1.6.1 (built from source) fails.
numpy 1.6.2 (built from source) succeeds.
numpy 1.7.0b2 (built from source) succeeds.
numpy 1.7.0 (built from source) succeeds.
numpy 1.7.1 (built from source) succeeds.
numpy 1.8.0.dev-e11cd9b (built from source) succeeds.

That all looks nice and neat, but according to my notes (and the
earlier email) the old numpy 1.4.1 on this machine was failing.
(I've erased that install now, but it was likely built with a
older Python 2.7.x and/or slightly older gcc).
