Comment (by Steven R. Brandt):

I'm wondering if we want an option to the build system (maybe some environment variable) to disable the automatic building of packages if something isn't found, i.e. HDF5, lapack, etc. It's really annoying to find the build system compiling HDF5 when I think I've set things up so it won't.
