I don't know if this is a real error path, or if it's just accumulating a bunch of warnings to print to stderr (i.e. if we just took out the offending line, would the program work anyways, or is the missing/old/unable-to-compute-version dependency actually important?).

This sort of problem reinforces my feeling that our {{{__init__.py}}} is way too complex, and that all the version-checking logic may be doing more harm than good.

This may provoke a 1.8.3, if it happens frequently enough. If the bad {{{e.__class__.name}}} is only triggered under weird combinations of installed dependencies, then we might be able to put it off until 1.9.0 .
