Well... this may be a red herring after all, but it's an interesting one!

It turns out I have got DYLD_LIBRARY_PATH set. This gets exported to R (or rather, affects the loader that loads the R process?), and somehow mixes up the way symbols are exported. Something that applies to launching R from the command line (/usr/bin/R) AND via LaunchServices (open -a R). Once I noticed that invoking the R GUI like that also provoked the issue, I quickly understood that something in the environment must be involved.

Unsetting DYLD_LIBRARY_PATH restores normal behaviour.

Note that this never caused any problems on 10.3 (and I'm not completely convinced there hasn't been a recent update to dyld that may be the culprit).

I still don't understand how this could make a symbol unavailable that is stored in some sort of internal registry.

However, while rebuilding 2.3.1 from source (!, but this one worked for me), I did notice that the configure script doesn't correctly detect that gcc-4.0 knows of the visibility attributes. This *may* somehow be related.
