-----------------------------+----------------------------------------------
 The bootstrap.sh script that comes with cabal-install is documented as
 respecting a PREFIX environment variable, but if you pass one it will
 ignore it during the installation of the executable:

 {{{
   ./Setup configure --user "--prefix=${HOME}/.cabal" \
     --with-compiler=${GHC} --with-hc-pkg=${GHC_PKG} \
     ${EXTRA_CONFIGURE_OPTS} ${VERBOSE} \
     || die "Configuring the ${PKG} package failed"
 }}}

 But then respect it during the post-install self-test:

 {{{
 CABAL_BIN="$PREFIX/bin"
 if [ -x "$CABAL_BIN/cabal" ]
 then
 }}}
 ...
 {{{
 else
     echo "Sorry, something went wrong."
 fi
 }}}

 Which means that it always emits the "Sorry, something went wrong."
 message and not the success message when PREFIX was specified.  Also that
 it installed into the wrong directory.
