I have tried to reproduce this, but without success. What I did was to
let Dorsal build OpenMPI, PETSc, and DOLFIN using the attached platform
file. I did see some similar warnings like
CMake Warning at demo/la/eigenvalue/cpp/CMakeLists.txt:31 (add_executable):
Cannot generate a safe linker search path for target demo_eigenvalue
because files in some directories may conflict with libraries in implicit
directories:
link library [libumfpack.so] in /usr/lib may be hidden by files in:
/work/johannr/dorsal/Work/FEniCS/lib
link library [libamd.so] in /usr/lib may be hidden by files in:
/work/johannr/dorsal/Work/FEniCS/lib
Some of these libraries may not be found correctly.
but nothing related to OpenMPI and PETSc.
Anyway, these are just CMake warnings and, unless you see some strange
behavior, can safely be ignored.

Title:
Incorrect path for link libraries from PETSc
Status in DOLFIN:
Confirmed
Bug description:
The correct path is not being added for some link libraries provided
by PETSc (specifically, those provided by PCC_LINKER_LIBS).
I see this when building PETSc and DOLFIN using a locally installed OpenMPI.
The consequence is that during configuration I get
messages like
Cannot generate a safe runtime search path for target
dg-advection-diffusion-demo because files in some directories may conflict
with libraries in implicit directories:
runtime library [libmpi_f90.so.0] in /usr/lib may be hidden by files in:
/home/gnw20/local/lib
