sorry about that

we have ran into similar issue and I believe we have it fixed in

    BF: explicitly check for ability to load liblapack.so and not enable test for dgesvd otherwise

and on Debian systems liblapack.so could be obtained via apt-get install

would you be so kind to check if current master works for you?

since you have already installed it from source it should be very easy,
and ideally done from GIT if you have one available:

git clone git://github.com/PyMVPA/PyMVPA.git

or just download from 
top buttons (Download as .zip , as tar.gz)

as a workaround I believe you could also try creating 
~/.pymvpa2.cfg with

have ctypes = no

which should mask out that feature so it would not puke on you

I would appreciate if you report back either current master resolves the
problem for you
