i installed ruby 1.8.6 instead… and now i’m trying to install mongrel,  
and it says ‘ruby lib version (1.8.5) doesn’t match ex’

is there a way to edit the mongrel gem, or am i screwed until there’s an  
update for mongrel?

or should i do the dreaded install of 1.8.5, then mongrel, then 1.8.6

reinstall mongrel – any native c code (and mongrel does include  
some) will need to be recompiled for new versions of ruby.
