Yes I will up come with a test program, but after the conference next 
week :) But just for my information: What failed on mac buildbot before 
adding the lines:

if get_architecture() == 'darwin':
         libs += " -lmpfr -lboost_thread"
     return libs

in the cgal.py package configurator? Was is  just because of the missing 
lines? libCGAL already is linked against the libs, so there should no 
need to add this directly, should there? From DOLFIN's point of view it 
is only interesting if a (functional) libCGAL is available.

Another question about the dependencies of dependencies problem :)
Since CGAL (and surely) also other third-library packages used by DOLFIN 
also depends on some libraries such as boost_thread and libmpfr that are 
not installed by default, we should somehow deal with these 
dependencies. Of course we can not take over the work of a package 
manager which resolves all the dependecies automatically. But maybe we 
should add these packages at least in the platform specific remark about 
preliminary packages in dorsal? Or make the dorsal CGAL build fail if 
the needed libs are not available?

Bug description:
The following changeset prevents dolfin from building on my mac because it doesn't have libboost_thread. It does build and work fine without it though.
