[R-SIG-Mac] Setting PATH in ~/.Renviron gives a different result in R64.app compared to result from R run in Terminal

[Berend Hasselman]

I have a ~/.Renviron file to set some environment variables.
The contents are

 ~/.Renviron  contents
-----------------------------------
R_LIBS_USER="~/Library/R/%v/library"
PAGER="/usr/bin/aless"
PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin"

Using Sys.getenv  in R from the command line  (Terminal) gives

> Sys.getenv("PATH")
[1] "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin"

But the same command in R64.app GUI gives

> Sys.getenv("PATH")
[1] "/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin:/usr/local/bin"

/usr/local/bin has been appended to the value specified in .Renviron

This also happens in a clean guest account.

What's going on?
