'aptitude purge fglrx*' fixed it, ie. the error message does not appear
anymore.

Shouldn't fglrx* packages be tagged conflicting to libgl1-mesa-dri then?

How would I utilize "Display driver for the ATI Radeon and FireGL
graphics accelerators" (from the package desription of fglrx-driver)?

Is this in fact a bug of fglrx 'messing up my libGL'?
