Installing lapack for numpy

Question

Running Ubuntu 11.10 + python2.7...built numpy from source and installed it, but when I go to install it, I get

ImportError: /usr/lib/liblapack.so.3gf: undefined symbol: ATL_chemv

when it tries to import lapack_lite from numpy.linalg. I tried to rebuild lapack from scratch, but it seems to just make

/usr/local/lib/libblas.a
/usr/local/lib/liblapack.a
/usr/local/lib/libtmglib.a

and the .so file. Where does the .so.3gf come from, and how do I fix it?
