Comment (by fbissey):
OK I think there may be niceties in the linker. Here I get:
{{{
creating /tmp/tmpRM4d1X/tmp
creating /tmp/tmpRM4d1X/tmp/tmpRM4d1X
compile options: '-c'
cc: /tmp/tmpRM4d1X/source.c
cc /tmp/tmpRM4d1X/tmp/tmpRM4d1X/source.o -L/home/fbissey/sandbox/git-
fork/sage/local/lib -lcblas -o /tmp/tmpRM4d1X/a.out
FOUND:
libraries = ['cblas']
library_dirs = ['/home/fbissey/sandbox/git-fork/sage/local/lib']
language = c
define_macros = [('HAVE_CBLAS', None)]
FOUND:
libraries = ['cblas']
library_dirs = ['/home/fbissey/sandbox/git-fork/sage/local/lib']
define_macros = [('NO_ATLAS_INFO', 1), ('HAVE_CBLAS', None)]
language = c
}}}
So we have only `cblas` again. But my linker still resolves it from the
information in the `cblas` library.
I think there is a small bug (feature) in `numpy` that causes it to only
use a single library. I think I now which part of the Gentoo patch deals
with that,
