The following forum message was posted by tfry at http://sourceforge.net/projects/rkward/forums/forum/165574/topic/3528988:

Basically the R_HOME check tries to run
[code][i]/your/path/to/R[/i] "--slave" "--no-save" "-e" "cat(R.home())"[/code]
and expects a non-empty result.

Which version of R is that? Did you use the installer from www.r-project.org,
or something else? Note that [i]/your/path/to/R[/i] should be the command-line
version of R, not R.app. IIRC it was located at /usr/bin/R by default. So, if
the "Looking for R executable" step picks up R.app or anything else, try adding
[code]-DR_EXECUTABLE=[i]/your/path/to/R[/i][/code]
to your cmake command line.
