Vinicius's approach his makes sense to me - we only need to test wtforms on the 
version of Python in Guix, not all possible versions the library supports. 
Would you be able to proceed with calling the tests as Vinicius describes?

This is the last dependency we need to package MediaGoblin! Very exciting!
