I initially thought that it would be a good thing, however now I'm thinking that it's leading to some kind of conflict between the build system and the bootstrap system.</div>
<div><br></div><div>In the past I've noticed that cabal does not deal well with different versions of GHC, particularly that it doesn't keep track which version of GHC is used to build and register a package (and the .cabal user directory doesn't have separate subdirectories for different cabal versions). This is quite annoying, since it means one can't really have test installs of GHC without fiddling around with prefixes or sandbox construction. Anyway, I wouldn't be surprised if conflicts from that sort of thing could cause the issue I'm having.</div>
<div><br></div><div>So I suppose the question now is, what is the actual cause and should it be fixed in GHC's build system or in cabal's source?</div><div><br></div><div>Thanks,</div><div>William</div><div><br></div>
