Problem with igem/gem in latest ironruby from github?

Hi,

i’m using the latest ironruby from github, and when i try to run igem
install it just fails with the following message:

D:\Projects\ironruby\bin\Debug>igem install rspec
ERROR: http://rubygems.org/ does not appear to be a repository
ERROR: Could not find a valid gem ‘rspec’ (>= 0) in any repository

any ideas? it works with the 1.1 alpha 1 release, but i had to upgrade
to
ironruby from github for some 1.9.x fixes

brs,
Davy
