The Python packaging rules have been recently changed wrt how .pyo files are packaged: they should no longer be %ghost'ed but made part of the package as is. Please see http://www.fedoraproject.org/wiki/Packaging/Python#pyos This package has %ghost'ed .pyo files. Please update it. Thanks!
Hmm. python-nltk is no longer the reference release upstream, it's been replaced by nltk-lite. I'll probably do an interim update that fixes this until I get around to packaging the new version.
Was hoping I could push nltk-lite and retire this, but since nobody's gotten around to reviewing it yet, python-nltk has been updated for now
