I've now done 1.18 and 1.20 cabal-install releases that should hopefully
fix this.

I’m not sure if I understand the problem. I believe bootstrap.sh should be expected to be run only on a bare system with nothing but GHC installed. If the user is already able to install Cabal packages, i.e. has some version cabal-install, they should be using that, not bootstrap.sh. Does this assumption simplify the problem you’re seeing?

In fact I don't know if I can get bootstrap.sh working at all. Without actually using cabal-install to do the dependency/flag resolution and make sure we build using a consistent set of packages we end up in problems like these:
Distribution/Client/HttpUtils.hs:68:43: Couldn't match expected type ‘network-2.4.2.3:Network.URI.URI’ with actual type ‘URI’ NB: ‘network-2.4.2.3:Network.URI.URI’ is defined in ‘Network.URI’ in package ‘network-2.4.2.3’ ‘URI’ is defined in ‘Network.URI’ in package ‘network-uri-2.6.0.1’ In the ‘rqURI’ field of a record In the expression: Request {rqURI = uri, rqMethod = GET, rqHeaders = Header HdrUserAgent userAgent : ifNoneMatchHdr, rqBody = ByteString.empty}
See full log: http://lpaste.net/116892
The cause is the HTTP package and the Cabal package being compiled against different versions of network. Given how bootstrap.sh works there's no real avoiding this. We can only hope that the user only has one version of network installed.
