You are using the wrong compiler and including the mpiuni directory.

Compilers:
  C Compiler:         mpicc  -fPIC -Wall -Wwrite-strings
-Wno-strict-aliasing -Wno-unknown-pragmas -O
  Fortran Compiler:   mpif90  -fPIC -Wall -Wno-unused-variable
-Wno-unused-dummy-argument -O
Linkers:
  Shared linker:   mpicc  -shared  -fPIC -Wall -Wwrite-strings
-Wno-strict-aliasing -Wno-unknown-pragmas -O
  Dynamic linker:   mpicc  -shared  -fPIC -Wall -Wwrite-strings
-Wno-strict-aliasing -Wno-unknown-pragmas -O
MPI:
  Includes: -I/usr/lib/openmpi/include -I/usr/lib/openmpi/include/openmpi


Use a PETSc makefile or get the compiler and include paths from PETSc. This
mpicc appears to be a valid MPI-2 implementation so everything should work
with it.
