Hi list

I want to use Numpy with Gnuradio but I cannot make it work. The
problem, which turns out to have nothing with Gnuradio to do, is an
undefined symbol as witnessed by these messages:

ImportError: /usr/lib/python2.6/site-packages/numpy/linalg/lapack_lite.so:

>>> quit()

My distribution is openSUSE 11.1 and what really bugs me is that the
exact same setup works as expected on another PC also running openSUSE
11.1. As far as I can tell, the installed packages are exactly the
same, version numbers, build dates, etc, all are the same... The only
difference between the two PCs is that the one (the one that fails) is
a new install and the other is an upgrade from an older release.

I have googled high and low but not found anything that could bring me
further. I hope that this (collectively) all-knowledgeable list can
give me some pointers.

Kind regards,
