The current Intel Mac binary that is available in BioC 3.16 is unfortunately
dynamically linked to libgfortran.5.dylib and won't load on an Intel Mac
that doesn't have Coudert's gfortran.
Adjustments have been made on lconway to address this. From now on, the binary
packages produced by the machine should work on a user machine that doesn't
have Coudert's gfortran.
