Hi All,
I still get these (related) errors. My setup is
Python 2.5
OS X 10.4.8 PPC
Numpy 1.0.1.dev3436
Scipy 0.5.2.dev2316
Latest xcode compilers with gcc_select 4.0.1
gnu fortran gfortran 4.2.0 20061007
on this platform, LAPACK/BLAS come from the altivec and accelerate framework
Does anyone else see this?
Andrew
