Not really an answer to your question, but...
I've found that in most cases checking for a minimum version isn't as useful as it seems, for one or more of the reasons below:
In most cases if an external tool doesn't support a feature it'll probably exit with an error when you call it, and you can just print an error at that point.
If it's really important to know in advance, do a test for the actual feature, not just a version number.
And, even though people might not read it, clearly add the dependencies to the documentation.
