I think hs-attoparsec and its dependents might need a revbump. Can you attach the output of ghc-pkg check and ghc-pkg list, please?

Replying to cal@…:

Done, see attachments.

[neverpanic (Clemens Lang)]

For each package that you have twice in the output of ghc-pkg list, please run sudo ghc-pkg unregister $name-$version where $name is the package name and $version is the older version of the package.

In your case that's

• highlighting-kate-0.5.3.9 and
• binary-0.5.1.1

These problems are caused by a bug in the haskell PortGroup which previously wouldn't successfully remove packages from the list while uninstalling them from MacPorts when there were still other (haskell) packages using them. This bug has since been fixed, but I cannot automatically fix that for packages that have been broken by it.

I've revbumped hs-attoparsec and its dependencies in r114665. That might or might not have been necessary, but since I have done lots of incorrect updates for haskell ports some unneeded revbumps probably don't hurt anyone to come back to a consistent state (especially since the buildbots will produce packages for those).

I think this problem should be fixed. Please re-open if you still encounter it.
