r27471 wasn't entirely correct: the libmpi_f90_so_version should have
been updated to 4:0:3 (not 4:0:1). The commit message stated that we
''changed'' and interface in 1.6.1, but that wasn't quite correct.

The change was a compile-time issue, not a link-time issue. It
changed a parameter from being INOUT to IN, but that doesn't change
the link-time semantics.
