Hello, I've just run across a fairly confusing error message when running 'cabal install': Warning: cannot determine version of /usr/local/bin/ghc : "" cabal: ghc version >=6.2 is required but the version of /usr/local/bin/ghc could not be determined. This error only appears with the install command, apparently when Cabal is run from a directory where it cannot write files (I was under /sys/, but the same goes for e.g. /usr/ as a non-root user). If possible, I think the error message should be clearer (it took me a while to figure out what was going on, and Google had no hits for that error message). I'm running under Debian Unstable, with ghc-6.8.1 and a very recent Cabal Darcs build. Unfortunately, I cannot try reproducing that glitch on the latest Cabal release. Thanks! Anthony
