Comment (by smaret):

 Replying to [comment:7 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.

 Thanks for looking into this. I've tried to set FC in a pre-build block
 (with an export) but it didn't work either. The only solution I could come
 up with is the following:

 {{{
 build {
     system -W ${worksrcpath}  "${build.cmd} -j${build.jobs}
 FC=${configure.fc} ${build.target}"
 }
 }}}

 Not very elegant, but it works.
