Comment 8 for bug 60103

Have the same problem...

xlibmesa-glu-dev package isn't available and libglu-dev, but here is what I get after running sudo apt-get install libglu-dev in a terminal:

Reading package lists... Done

Reading state information... Done
Note, selecting libglu1-mesa-dev instead of libglu-dev
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:
  libglu1-mesa-dev: Depends: libglu1-mesa (= 6.5.1~20060817-0ubuntu3) but 6.5.1+cvs20060824 is to be installed
