cabal output

When I run setup configure on my machine I get: Configuring Cabal-1.1.7... unrecognized option `--numeric-version' Try the option `--help' on its own for more information. setup: executing external program failed (exit 1) : /usr/bin/c2hs --numeric-version This is a bit confusing, because at first glance it looks like setup failed. I find this slightly annoying. Could we have it print "setup was successful" or something similar, just so we know for sure? I mean, we're already printing out the "Configuring Cabal..." message, so I don't think one more line is too wordy :) Pete
