[R-SIG-Mac] R/Cocoa and DYLD_LIBRARY_PATH

So, I've been playing around with the R/Cocoa that Stefano posted and I
think I have a reasonable solution to the DYLD_LIBRARY_PATH problem.
For those playing along with our home game the basic problem is that
the packages built pre-install are linked against 'libR.dylib' rather
than a full path, as is the case with post-install packages which are
linked against the installed framework (so they have a full path). The
problem is that you cannot set DYLD_LIBRARY_PATH from within your
program---dyld reads and processes DYLD_LIBRARY_PATH and friends before
main() executes. While you can set an environment variable in the
debugger, real users won't be running in the debugger.
To get around this problem in my personal install I went through (by
hand *sigh*) and used install_name_tool to change libR.dylib to
seems to do the trick and it seems like it would be pretty easy to add
to the install process.
