Fair enough - *but*:
I have a working (old)  scipy in site-packages (the one
which I use for real work.
All testing installs of numpy and (new) new scipy go to some other place
(~/BUILDS3/Build_113/inst_numpy, ~/BUILDS3/Build_113/inst_scipy)
These two directories are pre-pended to my python path
and if I had installed (new) new scipy then the import should
have found the right one.

Removing the `try: import scipy.linalg except ImportError:`
from `site-packages/numpy/linalg/__init__.py` cures the
problem (all tests pass).
(Actually, this was already adressed in Fernando's mail before).

yes I did. (but you convinced me before ... ;-)
