I was actually thinking about the circular dependency issues and
planning to do something very similar to you. Cool that there's priors. :)

But I'm mostly worried about libstdc++ (which would limit this
to C++-using packages following the earlier suggetsion that people
would like to avoid an extra dependency for C code). Although
since the potential for ABI trouble is so huge, I wonder whether
using shared libstdc++ is worth it to begin with when using pkgsrc gcc.

Agree.
