BLACS had been a part of scalapack for a few releases - so thats not the issue.

scalapack is getting compiled with this flag '-Df77IsF2C'.  This mode
was primarily supported by 'g77' previously - which we hardly ever use
anymore - so this mode is not really tested?

What do you have for:

cd /cm/shared/modulefiles/moose-compilers/petsc/petsc-3.6.4/gcc-opt/lib/
nm -Ao libscalapack.a |grep -i blacs_gridinfo

However - as Matt refered to - its best to use latest petsc-3.7
release. Does MOOSE require 3.6?
