[Haskell-cafe] Documentation bug -- building ghc from darcs sources

[Michael Vanier]

I've been trying to build ghc head from the darcs repo using these 
instructions:

http://hackage.haskell.org/trac/ghc/wiki/Building/GettingTheSources

Unfortunately, when I do

./darcs-all --extra get

as described under "Getting more packages" it fails because the 
darcs-all script doesn't recognize the --extra option.  Was this removed 
recently, and if so, how do I achieve the same effect?

TIA,

Mike
