hpricot and Ruby 1.8.7

So the problems from my Ruby 1.8.7 upgrade aren't over yet...! None of the Rails scripts (including script/server) will run from the terminal on my MacBook, because of an hpricot incompatibility. I've ignored it because everything still seems to work from RubyMine--I run the app there, and can do other things like script/generate. But I decided to try to fix it anyway.

Found a page that said yes indeed, hpricot and Ruby 1.8.7 don't get along, so I pulled down the git fork, tried to build and install, but had build problems with it (it was trying to build for an old darwin target, I think). So I tried pulling down and building Why's git repo per the instructions. Sure enough, that built and installed a new hpricot version--apparently the gem is not up to date.

Some notes: You'll need ragel, which can be installed via macport, and fast_xs, which is available as a gem to build and install hpricot.
