Hi all,
I'm going to look at this too. I couldn't find any patch or
information on what the bug is. Debian is migrating to version 3.8,
and we have the possibility of merging in from debian:

from the debian changelog:

   * Removing debian/used_lapack_version in clean
   * Use the changelog from liblapack-dev to find the current lapack version as
     we don't build-depend on the lapack3 package.

that liblapack library is mentioned in the mail exchange that Cyrus
pointed us to. We can try to put a PPA up of the debian version and
test if that works ok.
