I unmerged eselect-cblas and eselect-blas when I had similar problems, and I think also {blas,cblas}-reference. The eselect packages got remerged automatically, and some block I do not remember remained, but after some days, a deep world update finally was working again. > Not sure that was a good idea because now, even if I've reinstalled > these packages, > I am having several new problems: > > - compiling gcc with the gsl library spits out errors like: > g++ -L/usr/local/lib -lm -lgsl exact.o > /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../lib64/libgsl.so: > undefined reference to `cblas_ctrmv' [...] > and so on....... > > - still can't re-emerge packages like gsl and gmsh.

Stop. This looks strange. A target in the root file system? Here the log continues like this: [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 [100%] Built target gmsh >>> Source compiled. >>> Test phase [not enabled]: sci-libs/gmsh-2.5.0 > Does anyone have an idea of how solve this problem? No. All I can say is that I just emerged gmsh without problems on ~amd64, both with and without the blas USE flag. The other USE flags are those: Installed versions: 2.5.0{tbz2}(23:10:59 26.08.2011)(X blas jpeg png zlib -cgns -chaco -doc -examples -lua -med -metis -mpi -netgen -opencascade -petsc -taucs -tetgen) Wonko
