After two days of installing, reinstalling, updating, downgrading,
wailing, gnashing of teeth, and a heavy dose of wine, the cause of the
problem, and probably the only meaningful difference between the two
computers initially, was this line in the development computers /etc/
profile:

export RUBYOPT=rubygems

That's it.

In the process of tracking this down, I updated to the latest patch of
ruby 1.8.6 (287) on both machines, and installed ruby in /usr/local on
the production box (rather than using the Apple provided version as I
had been doing). But Ruby versions, Gem versions, gems installed...
none of it mattered. That line was the only thing missing.
