Bugzilla Bug 167652

When emerging numpy 1.0.1-r1, the build fails because it can't find cblas.

Reproducible: Always

Steps to Reproduce:
1. emerge numpy

Actual Results:  
>>> Compiling source in /home/tmp/portage/dev-python/numpy-1.0.1-r1/work/numpy-1.0.1 ...
 * You need to set cblas to atlas or reference. Do:
 *    eselect cblas set <impl>
 * where <impl> is atlas, threaded-atlas or reference

!!! ERROR: dev-python/numpy-1.0.1-r1 failed.

Expected Results:  
Um, I expected it to build...

I've tried "eseclect cblas set" with all of the suggested choices.  The numpy
build fails with all of them.  I have all of the following installed:

app-admin/eselect-cblas 0.1
sci-libs/cblas-reference 20030223-r1
sci-libs/blas-atlas 3.7.11
sci-libs/lapack-atlas 3.7.11

The command "eselect cblas list"
shows nothing:

 # eselect cblas list
 #

It looks like the versions of cblas you have installed do not support the
eselect cblas. You need at least blas-atlas-3.7.11-r1 or
cblas-reference-20030223-r3. Let me know if it still doing it after updating
your cblas lib. I updated the numpy ebuild accordingly no matter what.

Doh! I should have thought of that.

After unmasking ~x86 versions of blas-atlas and cblas-reference, numpy built
fine.

closing then.
