All of us over at ELCTech recently upgraded to RubyGems 0.91, only to find the following error during "gem" operations:

$ sudo gem install acts_as_ferret
ERROR:  While executing gem ... (NoMethodError)
    undefined method `refresh' for #<Hash:0x127c854>

Apparently the format of the gem cache files have changed, the new version cannot read some older versions of the cache. To fix this problem, delete your source_cache files in the following locations:

sudo rm /usr/local/lib/ruby/gems/1.8/source_cache
rm ~/.gem/source_cache

Looks like someone forgot to think about us old folks with ancient versions of RubyGems. In the future, I'll plan on running "gem update --system" more often!
