 Replying to [comment:5 i0ntempest]:
 > I thought compiler path is no longer baked in and we no longer follow
 the upstream guideline that says R base and packages should be built using
 the same compiler?

 As of now it is, AFAIK. Unless someone changed that without me noticing.

 > If this is the case how much stuff do we need to rebuild?

 I recall rebuilding was pretty unpopular last time and I rather avoid
 another week-long discussion, so let others decide. I can always fix this
 for myself at least.

 P. S. As a matter of fact, a number of ports have been broken earlier by
 skipping revbump when it was due. So I had to add these hacks whenever CI
 shown an error: https://github.com/macports/macports-
 ports/commit/622eca8499b7d482142030eb8d61c0ff01a011c8
 Those are not numerous, given total number of R ports, but there may be
 more.
