What do you want the `tree' function to `perform'?  Let me guess that you
want a clone of S-PLUS.  In that case the nearest equivalent is in package
`tree' (surprise, surprise) loaded by library(tree), *but* we recommend you
to use the facilities of package rpart, which should be in all binary
distributions of R.

That's a Mac-specific problem (more than 90% of packages compile out of
the box on Unix, Linux and Windows), and your report is far too vague to
make a useful comment on.
