Following Michael Mol's advice I masked these in /etc/portage/package.mask:
>=virtual/blas-2.0 >=virtual/cblas-2.0 >=virtual/lapack-3.1 >=sci-libs/cblas-reference-20030223-r5 >=sci-libs/lapack-reference-3.2.1 >=sci-libs/gsl-1.14 and did an "emerge -uD world". All blocks were gone and after the emerge I got gsl working again. I am also not sure what use is eselect-cblas since eselect blas works without it. gmsh still won't emerge with these types of errors: ... [100%] Building CXX object CMakeFiles/gmsh.dir/contrib/bamg/bamglib/Meshio.cpp.o [100%] Building CXX object CMakeFiles/gmsh.dir/contrib/bamg/bamglib/QuadTree.cpp.o [100%] Building CXX object CMakeFiles/gmsh.dir/contrib/bamg/bamglib/SetOfE4.cpp.o Linking CXX executable gmsh CMakeFiles/gmsh.dir/Numeric/fullMatrix.cpp.o: In function `fullMatrix<double>::invertInPlace()': fullMatrix.cpp:(.text+0xcc): undefined reference to `dgesv_' CMakeFiles/gmsh.dir/Numeric/fullMatrix.cpp.o: In function `fullMatrix<double>::gemm(fullMatrix<double> const&, fullMatrix<double> const&, double, double)': fullMatrix.cpp:(.text+0x1e9): undefined reference to `dgemm_' CMakeFiles/gmsh.dir/Numeric/fullMatrix.cpp.o: In function `fullVector<double>::axpy(fullVector<double> const&, double)': fullMatrix.cpp:(.text+0x260): undefined reference to `daxpy_' ... So making some progress.
