The trouble is that the boot scripts use GNU specific features. I was the one that changed it to bash because I was tired of the build breaking on Solaris. I think the original problem was that the Solaris version of 'test' doesn't support some of the flags being used, but I'm sure there are others.
The GHC build system is packed to the gills with unnecessary dependencies on GNU utils (including bash). More detail is at http://hackage.haskell.org/trac/ghc/wiki/Building/Solaris. Though I agree it would be nice if it was made more portable, trying to make shell scripts more portable is a losing battle. Also, I don't think people validate it enough on non-Linux platforms as it is, so GNUisims would just creep in again. Please don't change it back to sh unless you've also validated the change on at least OSX, Solaris, Windows and Linux as well as your own platform. Ben.
