Firstly -- I don't think this is the best list for you to be seeking
help in. I guess this is more geared to the list for rpy:
But, let's see ...

This "make command not found" business sounds like you don't have
XCode installed on your mac, which you'll need.
In addition to the "xcode install" installing the XCode IDE, you'll
also be installing tools you'll need to build software (like `make`
and `gcc`, etc).

I'm not sure that R isn't "sharing it's library" from the error you
provided above ... is there another error popping up as well, or?

Try installing XCode and redo.

Yeah, you've got the correct R_HOME, but none of those instructions
seem right for OS X.
For instance, you'll realize that there is no file named "libR.so" in
"/Library/Frameworks/R.framework/Resources/bin" -- in fact, I guess it
would be in "RHOME/lib" .. but I guess you also have to deal with the
architecture stuff on os x, like i386 vs x86_64.
So ... I'd follow upon the rpy list I think.
