YMMV but i had some trouble with gem executable conflicts using the
program-suffix scheme.  Also with she-bang lines in scripts.

I've had much less trouble with 1.9 in its own sandbox (e.g. under
/usr/local/ruby-1.9) and a little script to modify my $PATH whenever i
want to switch between 1.8 and 1.9.

And for the sake of completeness i should mention macports has a
ruby19 package (which installs with the aforementiond suffixes by
default).
