No this was regular (not j-) ruby, 1.8.7.
I think my problem was related to rubygems, at the time I still had
1.3.5.

Later I installed rvm and, again using ruby 1.8.7, I had more luck
doing a fresh start by first updating rubygems to 1.3.6 and then
running only gem install rails --pre, which automatically grabbed all
the gems needed. This way it grabbed memcache_client 1.7.8 (not 1.8.0)
and the whole thing worked without a hitch.

So I'd replace the advice listed on the guides with:
1) update rubygems to 1.3.6 (gem update --system #or whatever
equivalent you need to do so)
2) then do: gem install rails --pre

With ruby 1.8.7 on snow leopard, that's all it needs.
