I sorted the scalapack problem by leaving the SCALAPACK variables blank and adding the static scalapack library to the "RP Parallel-Libs for gfortran:" field, however this will not work for static FFTW where the includes and def are needed as well and defining those would already force the dynamic linking flags. Editing Makefiles is fine, however the annoying thing is that I can't do any further changes with siteconfig later, since everything will be regenerated :-( I agree with prof. Marks that it would be definitely nice to have, but I understand that only few people do this. I believe the new siteconfig is better for new users, however the static linking was definitely easier before. BTW if you use link time optimizations for everything, the compiler should be able to optimize away the unneeded symbols and functions so that the resulting binaries are quite small (+ there might even be some extra optimizations possible due to stuff like inter-library inlining, however this is probably negligible).
