[Sébastien Villemot]

Package: src:dune-pdelab
Version: 2.0~20140205g0cee0ce-1
Severity: serious
Forwarded: https://dune-project.org/flyspray/index.php?do=details&task_id=831

Dear Maintainer,

superlu 4.3 has been uploaded to unstable. The -dev package is now
libsuperlu-dev (it should be updated in your Build-Depends and in the Depends
field of libdune-pdelab-dev).

Unfortunately, dune-pdelab FTBFS against superlu 4.3:

There is a name clash between headers from libalberta2-dev and libsuperlu-dev.

According to the upstream bug report, alberta has renamed the function in
recent source snapshots (and maybe in 3.0-rc7 available for download, this
needs to be checked). So the right solution is probably to update alberta in
Debian.

Cheers,
