You can also have a look at a tool called versigmsg, from my gocoin project.
https://github.com/piotrnar/gocoin/blob/master/tools/versigmsg.go
If you build it, it end up as a single executable, about 2MB big.

I released a Ruby Gem to verify signatures. More information:

Just noticed some tests at the bottom: https://github.com/jackjack-jj/jasvet/blob/master/jasvet.py#L551-L579
From a fairly quick skim through the code, it looks pretty straight forward as written (hahah, though a little more complex than I was hoping!). The rest of my weekend might be making a Ruby Gem for this. 
Do you have tests for this? I'd love to duplicate some of the tests also.

This is the Bitcoin signature/verification module I made for Armory:

The function you're looking for is verify_message_Bitcoin(address, signature, message), line 387
Example:

Is a python script (no dependency) ok to use?
Yeah, i'm actually looking to do it in Ruby, but i'm guessing i can convert what is thrown at me to my language of choice.
Is a python script (no dependency) ok to use?
If I have a Bitcoin address and a message signed with the private key of that address, is there a way to verify the signature with standard Unix commands?
