Subject: ri on snow leopard?

Hey all -

As usual after any kind of dramatic change on my computer, ri is
semi-busted after upgrading to Snow Leopard.

Possibly relevant:

$ ri --version
ri v1.0.1 - 20041108

(Seems oddly kind of old.)

Anyhow. Works fine like this:

$ ri --system String

[gorgeous display of results omitted here for brevity]

But:

$ ri String

Maybe something crufty left over from earlier? Any suggestions on how to
track it down? The --gems docs seem to be the problem, I think. Thx - m.
