From searching, len_trim is a fortran >95 function. g95 does support it.
It's hard to believe things would work so far if f2c (fortran 77 -> C
compiler) is being called, but it seems like the only reason it could
fail just for you.
netbsd's gcc has no fortran support either, pkgsrc's g95 or gfortran
nvidia published a llvm fortran compiler ~2 months ago:
but it's very early.
