Cryptic gem error message
I probably never noticed this before because I never happened to gem update without sudo prefixing the command on the iBook. I just accidentally did, though, and lo the - not so - informative message:
ERROR: While executing gem ... (NoMethodError)
undefined method `source_index' for #<Hash:0x283d464>
Not great…
