no, I think this is not the case

hmm, the fact is that just adding libatlas-base-dev to the build deps
list makes the configure script work. The explanation is a bit more
complicated and I had to drop in a shell in the pbuilder in order to
understand it. As far as I remember I tried to compile myself in the
pbuilder shell the same conftest which fails in the configure script
in order to realize that the problem was related to the linking of
liblapack3gf. Anyway I will try later to create a minimal test case
free of any mumps stuff demonstrating the problem.
