mpicxx.h(2806): error: more than one instance of overloaded function "MPI::Init" has "C" linkage

I am trying to compile openfoam 3.0.0 on centos 6.5 using intel compiler 15.0.3 and i am getting error:

make: *** [Make/linux64GccDPInt32OptIMPI/ptscotchDecomp.o] Error 2

since the error is related to intel's mpicxx.h ao i am posting this here.
please take a look on the full compilation procedure here:
