[gentoo-science] failure to merge sage due to unavailability of cblas

[Markus Oehme]

Hello,

I'm trying to emerge sage from the sage-on-gentoo overlay. Unfortunately
this always fails with errors like the following:

===
x86_64-pc-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,--as-needed -O2 -pipe -march=native -ggdb -fno-strict-aliasing /var/tmp/portage/sci-mathematics/sage-5.6/work/sage-5.6-python2_7/temp.linux-x86_64-2.7/sage/gsl/callback.o -L/usr//lib -L/usr/lib64 -lcsage -lgsl -lgslcblas  -lstdc++ -lntl -lpython2.7 -o /var/tmp/portage/sci-mathematics/sage-5.6/work/sage-5.6-python2_7/lib/sage/gsl/callback.so
/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.2/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lgslcblas 
collect2: error: ld returned 1 exit status
===

I have the science overlay installed. I understand that there are quite some
changes in the overlay on how the scientific libraries are handled -- so I
come here for help. ;)

I've installed both gsl and atlas and invoked eselect several times to make
sure, that everything is set up properly, but to no avail. I have a file
/usr/lib64/libgslcblas.so on my system, so I don't see what's wrong here.

Any clues appreciated. :)
