============================ Linking step-42 /home/frohne/deal-subversion/trilinos-10.4.2-mpi/lib/libepetra.so: undefined reference to `dgeequ_'

These are blas and/or lapack functions. You configured Trilinos to use these functions but unfortunately Trilinos doesn't store this information in the shared libs you link with and so when you compile the final program the compiler complains. Unfortunately, also, it's really difficult to find out when configuring deal.II that one of the libraries we link with (libepetra.so in this case) uses some other library (libblas or liblapack) and so deal.II doesn't know to put this on the linker line.
The only solution I see is for you to configure deal.II explicitly using --with-blas and/or --with-lapack to link with the same libraries as you've told Trilinos to do.
