>Description:
The port math/mpfr has been split off from the port math/gmp4 (see the PR
ports/84724).

Gfortran in GCC 4.0.x depends on the MPFR libraries.  Since GCC's configure
script does not detect MPFR, it does not build gfortran.

When installing lang/gcc40 with the WITH_GFORTRAN flag -- i.e., when
installing lang/gfortran -- the install therefore fails if math/mpfr was not
previously installed.

>How-To-Repeat:

[pkg_delete math/mpfr]
portinstall lang/gfortran

>Fix:

Add a dependency on math/mpfr to lang/gcc40 under the WITH_GFORTRAN
conditional.
