Hi Jan,
thx. Unfortunately what I after that realized is that I had some
problems with the boost-libraries in the first place. Thats why the
errors popped up. Do you have anything to comment on:
[...]
I got everything to compile finally, but an import of dolfin produces
the error ImportError: /home/phoenix/Work/FEniCS/lib/libdolfin.so.1.4:
undefined symbol: _ZN5boost6thread4joinEv
As brought up before this is due to the boost-package that is mengled up
and that I didn't compile before properly. A compilation of the latter
stopped with another error however. I guess that after that fix I
recompile dolfin one last time and then I am good to go. The
..Work/FEniCS/src/boost_1_55_0/dorsal_build.log ends with
...failed updating 45 targets...
...skipped 50 targets...
...updated 564 targets...
and can be seen in full glory here:

I succesfully compiled dolfin, but now when I try to import the

does the boost in the last line refer to the boost libraries? If yes
how do I set the paths correctly s.t. dolfin sees them?
Following
$ ldd fenics/lib/libdolfin.so | grep -i boost
must report correct libraries you used for compiling. ldd searches
in LD_LIBRARY_PATH. This is set in fenics.conf generated by Dorsal.
