Good catch.  The version comparison stuff probably needs some work, and 
I'm not sure I'm completely up-to-date on the Totally Correct way to 
compare version numbers/strings.  Do you know much about this?

(By the way, you probably should use 'build_requires' rather than 
'requires' for the Module::Build dependency.  I'm sure that has the 
same bug, though.)
