if you cd into the repo rvm kicks in at seeing the .rvmrc file then gets all complainey when you don't have the @repodepot gemset installed. I'd install it, but there's no .gems file for rvm so we can't easily recreate this theoretical @gemset
export the rvm @repodepo gemset to a repodepo.gems file
create a .gemspec
get rid of the .rvmrc file
I vote for either of the first two.
