hdf5-18: +fortran requires a fortran compiler to be selected

[smithsp (Sterling Smith)]

I issued the command

port upgrade outdated

At some point it failed, with the error:

Error: +fortran requires a fortran compiler to be selected

Error: Unable to open port:

Turning on debugging yielded:

The error message is probably correct. In addition to the +fortran variant, try specifying a fortran compiler variant (they are g95, gcc44, gcc45, gcc46, gcc47, gcc48, gcc49, gfortran).

Adding Sean to the cc list; perhaps this relates to the compiler/mpi group voodoo.

Cc Me!

In the end I was able to get things to work, I believe by indicating the desired variant of compiler for the hdf5-18 port as suggested by Ryan, which apparently I had not done previously.
