Hmm. Perhaps you should rename the long form of -L to --list-local-packages.

Just a small note: This was a buglet in System.Console.GetOpt.getOpt, which has been fixed since GHC 5.04.3. Consequently this does not happen if you use a GHC >= 5.04.3 for compiling GHC 6.0. But to be on the safe side, SimonM has renamed the option, anyway...

OK. The official ghc-6.0 binary distribution for Linux seems to have been built with ghc-4.08.2, hence the apparent fault. Was there a reason for choosing to bootstrap with such an old version?

The ghc-pkg utility was built with 4.08.2; GHC itself was bootstrapped. The reason is the new bootstrapping facility in the build system, which means that we don't have to compile the entire tree again for each bootstrapping stage - I hadn't considered that this might have disadvantages :-) Cheers, Simon
