There are some packages that has to be removed. For example:
- PinesoftEnhancementsForFreeType:� This package is empty
- FixUnderscores:� This package is old, is not needed any more and has no references

The fix is to evaluate:

(MCPackage named: 'PinesoftEnhancementsForFreeType') unload.
(MCPackage named: 'FixUnderscores') unload.

Cheers
