My *guess* is that it has to do, as you point out, a problem of
different compilers and mixed installations from binaries (R) and from
source, i.e. using different compilers and compiler versions.

I had similar troubles until I removed all remnants of the binary
installation of R and installed everything via homebrew (no experience
with MacPorts).

But then (just a guess), as far I understand MacPorts, they provide
binaries, and they not necessarily correspond to the same compilers you
have installed?

If this is really causing the problem, I guess you have to install
everything from source, which you ca do using homebrew.

Cheers,

Rainer
