Comment (by dstrubbe@…):

 Hello Takeshi,

 This would not solve the problem unfortunately. You can see in the log
 that we are already checking whether fftw-3 has a Fortran variant:
 {{{
 Error: Install fftw-3 with a Fortran variant.
 Error: org.macports.fetch for port octopus returned: fftw-3 not installed
 with a Fortran variant.
 }}}
 The problem is, that is not a default variant, and so the buildbot does
 not have fftw-3 installed with a Fortran variant when building octopus.
 mpi.enforce_variant would not do this either. Moreover, it is too
 restrictive, in that we do not need the same Fortran compiler as octopus,
 just some Fortran variant. Ideas on how to fix this situation are
 certainly welcome.
