Presumably there was a reason why you were searching for the package in the first place? A challenge that you were trying to overcome? If there's no perfect solution that exists (which there never is)--and if bringing in someone else's partial implementation "as is" doesn't work--then the only other options available are to write 100% of the solution yourself or to write (100-x)% of the solution yourself. Also, presumably, that you're not in the business to write library tools. So unless the broken OSS package is written in complete greek, why wouldn't it be more efficient to use it as a template for your solution?
