That's because R needs a fortran compiler to compile. It does not have a C
fallback solution for its maths. cantor depends on R per default. So it won't
build until a working R is installed.
Peter is not having problems without fortran. Everything compiles fine. So I am
quite shure he has neither R nor cantor installed or any other program that
needs a fortran compiler to build at all.
This euse command shows only packages where fortran is optional. This means
better performance, when enabled, in all (at least almost all) cases.

That's impossible, I think. euse reports USE-flags. These programs don't have a
fortran-USE-flag. R needs it unconditionally..
