I'm not sure what's going on here, but it has nothing to do with the checksum -- the import code doesn't ever look at the checksum.
The code determines what classes are in the archive by looking at the "faspac" property in the pkginfo file. If there are files it expects to find in the archive but aren't there, it'll go looking in the reloc directory. It seems that for some reason, it didn't find these files in the archive, and it didn't then find them in the reloc directory. Do make sure they're in the archive, and do make sure that the archive is compressed either with bzip2 or 7z, or the code won't find it. The archive also has a slightly funny file format, but I'm not sure if that really matters here. My guess is that you're not re-compressing, since you don't mention doing so in your email. Danek
