I think the difficulty here is that libblas.so and libblas.so.3 live in
different packages (-dev versus shared library).

Sorry I had overlooked your remark about HDF5. What is done there looks
a bit hackish, but if it works and is robust, why not…

Yes, somewhat of a hack, but it seems to work.

Note however that the libblas.so alternative should actually not matter
much. Since the various implementations are supposed to be ABI-
compatible, whichever is used at link time should normally be

True, so not so critical if they're different. The danger then is if admin sets the alternative for libblas.so but not libblas.so.3, and thinks the job's done.
