Hello, and apologies again for accidentally sending my previous draft message
to the
mailing list.
I am trying to build FEniCS on Kubuntu 14.04 using Dorsal, in order to try out
the CBC.block
demos. The build apparently worked, but I then discovered that various
components are
not properly configured. In particular:
1) Epetra is "found" but not "available".
2) petsc4py is disabled because of an apparent incompatibility between
PETSc version 3.5.2 and petsc4py version 3.4.
How do I fix these? I have tried to include all relevant details below.
All the best, Paul
