- update - 

Thanks for all the help -- Sebastien, Laurent, Guillaume !

After removing any remaining ppa's from etc/apt/sources.list.d I upgraded to
Ubuntu 12.4.

I then uninstalled cgal and all the qglviewer and qtopengl related libs.
Removing libqt4-opengl forced me to uninstall lots of stuff I'll have to get
back later, but, just to have a clean slate ...

I then ran aptitude to see if there were any conflicts left over and indeed,
even after the upgrade, it found a lot, especially a qtopengl lib that was
i386.

After that, installed CGAL from software center, is now version 8, yay.

When cmake-ing and make-ing the demos, the problem with the /usr/lib/
expectation is gone. Starts out like this :

lukas@heartofgold:/usr/share/doc/libcgal-demo/demo$
 sudo make

... 
and so on. But, a bit later :
...
[ 13%] Built target Circular_kernel_2
Scanning dependencies of target Circular_kernel_3
[ 13%] Building CXX object
demo/Circular_kernel_3/CMakeFiles/Circular_kernel_3.dir/Circular_kernel_3.cpp.o

and it breaks off. Have no clue what it's unhappy about now. Anyway, I had a
look at the AABB and AlphaShapes etc directories which make seemed to have
made happily, but found no executable. Was I mistaken to expect executables
or would those have been created later in the process? I saw that *.so
libraries of those demos got created in CGAL_ipelets (haven't installed the
CGAL ipelets package, do I need it to run the demos? ). 

The documentation seems to indicate there would be an executable in each of
the demo directories, if I understand it correctly?

I will have to reinstall FreeCAD, OpenFOAM, Elmer, Meshlab, etc. , so I'm
thinking these (or rather their ppas) could have been likely causes of the
library / make problem.

Also, the Ubuntu upgrade (or maybe the Aptitude tidy-up) removed GoogleEarth
64 bit, which I had installed from a .deb, and when I began to re-install it
through Software Centre, it warned my about all the libs that would install,
they were A LOT, all i386, and one of them was the qt opengl i386, so I
broke off the install.

Now, I'm stuck with the new problem from make, but also a bit in limbo
because I don't want to reinstall any of the software that may have caused
the original problem. 

Is anyone aware of known incompatibilities among the softwares I've listed?
I really need to reinstall FreeCAD, but I had a FreeCAD Devel ppa that's no
good for Ubuntu 12.4 at this point anyway, so I'd now install it from the
canonical repos.

Thanks again, everyone!
