[Rd] Assistance much appreciated

[peter dalgaard]

Presumably the file in question is one of

Peter-Dalgaards-MacBook-Air:BUILD pd$ grep -r "^Package: tools" *
library/tools/DESCRIPTION:Package: tools
src/library/tools/DESCRIPTION:Package: tools

so the first thing I'd do is to have a good look at those files and see if they got somehow corrupted.

If they look sane, presumably the bit of code that checks it isn't... So that would be my next thing to check.

In a previous post you listed a long list of warnings about packages not being loaded; that's likely a serious problem, but I don't know if it is the cause or a consequence of this one. Something is seriously wrong with the startup.  You could try debugging setup_Rmainloop in <src/main/main.c>. to see if any warnings are being generated there.  There shouldn't be any.
