This is very weird. Can you try to use the compiler separately? The 
following command will give you the internal compile options mpicc is using:

  shell$ mpicc -show

Can you send us the output for this, and also make sure the correct 
compiler is being used, the compiler works fine (by trying out some 
simple program), etc.?
