Argh, I missed that point because I went directly for a full gcc/gfortran recompile. This also means that you cannot fix Simon's gfortran-4.8 by replacing the libs, of course.

OK, but it is not really an attractive solution if it only works some of the time.

OK, I can try those on the laptop without too much hassle.
