It appears that your MANIFEST does not contain the same components that
are currently in the 'inc' directory. 

Please try running 'make manifest' and then run 'make dist' again.

Remember to use the MANIFEST.SKIP file to control things that should not
end up in your MANIFEST. See 'perldoc ExtUtils::Manifest' for details.
