Comment (by ryandesign):

 This port uses the compilers portgroup, which I have never understood very
 well, so it is difficult for me to know in advance what will work and what
 will not. Now that I look at it closer, I understand that the compilers
 portgroup creates variants for you to choose what compiler to use, and the
 code that chooses that compiler is in each variant. Variants get evaluated
 after the main part of the portfile has been evaluated, which is why
 adding `FC=${configure.fc}` to `build.args` in the main part of the
 portfile doesn't work right, because `configure.fc` hasn't been set by
 that point. But appending to `build.args` in a `pre-fetch` block wasn't
 right either, since the fetch phase doesn't need that information; the
 build phase does. So it should be done in a pre-build block.

 Unfortunately this port's build system evidently doesn't know to exit when
 an error occurs. It would be nice if we could fix that. But since this
 problem exists, we now have broken archives published on our packages
 server, and installed on some user systems, so when the above is fixed,
 the revision will need to be increased.

 I had filed similar tickets for other ports; maybe those ports have the
 same problems, so they should be checked as well.
