The steps needed to generate the error are: - install a binary distribution of R (default location) - add R to the PATHDid you actually add /Library/Frameworks/R.framework/Resources/bin/ to your PATH? You're not supposed to do that! What made you think so?
Coming from an UNIX background, adding a directory like bin/ to the PATH does not appear unreasonable.
This directory contains a range of support scripts for R which are not intended for direct use from the command line or other programs. In my installation, there's just a symlink from /usr/bin/R to the R binary in the directory above, which AFAIK is the only program you need to invoke directly.
I am relatively new to OS X, so I cannot tell whether this is an R specificity, or the way things are usually done on OS X are somewhat very different from the UNIX way. I am surprised by this cherry pick one executable in bin/ / don't touch the PATH.
In your case, R's "INSTALL" script, which implements the "R CMD INSTALL" functionality masks the standard "install" program in /usr/bin/install, so Python's installer now picks up a completely wrong program. Even if you edit R's "INSTALL" script, it'll do something entirely different from what you expect.
To my great dismay I am hearing here that Mac OS X is not case-sensitive.
BTW, putting the R binary directory ahead of system directories such as /usr/bin in your PATH is an even worse idea than including it there in the first place. ;-)
I am used to the fact that adding a bin/ directory in the PATH (and *ahead* of all other components in the PATH) is the way to add custom binaries. I cannot exclude that I am missing some specificities of Mac OS X, but that idea seems to be at least shared by the fink project (their default install puts /sw/bin ahead of all the rest).
I suppose that there is a documentation for R-on-OS-X and that I overlooked it.
