barchart is a command-line program with associated Haskell library

After announcing the barchart package, I have some problems building its Haddock documentation. Firstly,

The API is not generated on Hackage because the diagrams library cannot be built on GHC 6.12.

Hence, I tried to generate it myself, but

Even with

--html-location='http://hackage.haskell.org/packages/archive/$pkg/latest/doc/html'

'cabal haddock' does not generate links to the required packages.

I noticed, that 'cabal haddock' does generate (external) Links to Hackage when I use the --html-location option after reinstalling all required packages *locally*. Why do I have to istall local documentation in order to get external links? Secondly, there are no Haddocks for the Diagrams library on Hackage and, hence, the links from the barchart docs to Diagrams's types are broken. I'd like to specify a custom link target for only the Diagrams package (the Diagrams website has Haddock documentation). Is this possible?
