----------------------------+-----------------------------------------------
 When attempting to install cabal-install for the first time, on a unix
 system, using the supplied bootstrap.sh script, if anything goes wrong
 during the script, it carries on regardless, leaving the install process
 in an inconsistent and potentially unrecoverable state.

 I tried to install cabal-install for ghc-6.8.2, which was originally
 supplied with an older version of Cabal (1.2.3.0), on a Mac.

 For some reason (probably another Cabal bug), my existing $HOME/.cabal
 /powerpc-darwin-6.8.2 directory had the wrong permissions.  So when
 bootstrap.sh built Cabal-1.6.0.1 and tried to install it, it could not.  I
 fixed the permissions and ran bootstrap.sh again:  It built and registered
 Cabal-1.6.0.1 correctly this time, but did nothing else, except print the
 error "Sorry, something went wrong".  Running the subsequent script
 commands manually (to configure, build and install HTTP, zlib, and cabal-
 install) also did nothing.  For instance:

 {{{
 $ runghc Setup configure --user && runghc Setup build && runghc Setup
 install
 $
 }}}

 Note the lack of any output whatsoever.
