I’m following along with Peepcode’s guide to using Capistrano to deploy  
Rails apps right now, but I’ve hit a snag and I have no idea what to do  
to fix it. When I try to “sudo gem install railsmachine  
–include-dependencies,” the machine thinks for a few seconds, then  
gives me this funky error message:

ERROR: While executing gem … (NoMethodError)  
undefined method `refresh’ for #Hash:0x1107ff4

Has anybody seen this before? I honestly haven’t an inkling of what this  
means nor how to remedy it.

Thanks
