I’ll add that these issues crop up a lot on HPC systems where the native compiler is often too old to be much use for anything.  As a result, some sort of bootstrapping or manipulation of dependencies to avoid circularity in necessary.  Jason has captured much of this in his auto-pkgsrc-build script.  I think following path (1) would solve all of these issues; however, it would be a good idea to keep in mind this type of system when evaluating the options.
