Thank you Chris for pointing out that typo and providing a fix! I've uploaded a fixed package.
Thank you Adrian for your efforts too, however please be more careful in future, you uploaded a package with -2.1 as revision, but the package in unstable is -1 so you were supposed to use -1.1 as revision number. I had to upload two packages because I noticed this mistake after the first upload... Thank you again, Devid
