Comment (by zooko):

 Saizan on IRC told me about the {{{--package-db}}} option.  I tried it
 like this:

 {{{
 ./Setup configure --prefix=/usr/local/stow/Cabal --package-
 db=/usr/local/stow/Cabal/var/lib/package.conf
 Configuring Cabal-1.6.0.2...
 Setup: ghc-pkg dump failed
 }}}

 then I wondered if I needed to mkdir the path for it first, so I did:

 {{{
 mkdir -p /usr/local/stow/Cabal/var/lib/
 ./Setup configure --prefix=/usr/local/stow/Cabal --package-
 db=/usr/local/stow/Cabal/var/lib/package.conf
 Configuring Cabal-1.6.0.2...
 Setup: ghc-pkg dump failed
 }}}

 Then Saizan suggested touching it or echoing [] into it:

 That did it!

 {{{
 touch /usr/local/stow/Cabal/var/lib/package.conf
 ./Setup configure --prefix=/usr/local/stow/Cabal --package-
 db=/usr/local/stow/Cabal/var/lib/package.conf
 Configuring Cabal-1.6.0.2...
 Setup: ghc-pkg dump failed
 echo "[]" >> /usr/local/stow/Cabal/var/lib/package.conf
 ./Setup configure --prefix=/usr/local/stow/Cabal --package-
 db=/usr/local/stow/Cabal/var/lib/package.conf
 Configuring Cabal-1.6.0.2...
 }}}
