[Daniel Schepler]

Package: libgl1-mesa-directfb-dev
Severity: grave
Version: 6.3.2-2

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  libgl1-mesa-directfb-dev: Depends: mesa-common-dev (= 6.3.2-2) but it is not going to be installed
                            Depends: libgl1-mesa-directfb (= 6.3.2-2) but it is not going to be installed
E: Broken packages

The following packages have unmet dependencies:
  mesa-common-dev: Depends: mesag-dev (> 6) but it is not going to be installed or

It appears mesa-common-dev also needs to allow the directfb version as
an alternative.  (I discovered this in pbuilder builds -- this package
happens to be the last package listed as a reverse provider in
"apt-cache showpkg libgl-dev", so it's the one pbuilder tries --
unsuccessfully -- to install when it sees a Build-Depends on
libgl-dev.  Not that that isn't broken anyway, but several packages
currently have "xlibmesa-dev | libgl-dev", where the first is no
longer installable.)
