Thanks for your question. Your logs show that 'gcc' is not found. As
of R 3.3 you need to set the path to the compiler using the BINPREF
variable. This is because we ship two separate versions of gcc, one
targeting win32 and one targeting win64. I am not sure what your
rtools installation looks like, but could you try setting this
I think this will do the job.

This issue is unrelated, I doubt your advice will solve anything. The
only thing that 17376 does is add c:/rtools/bin to the default path.
But this dir does not exist for this user, so it is ignored by windows
when searching the PATH.
