whoa there. you only need _one_ mpi library, 
not three of them. how did you plan to distinguish
between them??

did you try to compile and run any MPI example programs
to verify that your MPI installation is correct and working??

please read what it says. it is a _WARNING_. that means
the configure script could not verify that you are using
a know to work combination of MPI and compilers. i.e. you
should go on and try to compile, but be very careful in 
checking that the resulting programs will work.

good luck,
