 Consider the following transcript.  Why is Cabal ignoring --destdir,
 and why does mandir default to \$prefix/share/doc/foo-1 instead of
 \$prefix/share/man?

 {{{
   $ darcs get http://twb.ath.cx/tmp/tinc
   Finished getting.
   $ darcs check --test --repo tinc
   [...]
   + ./Setup copy --verbose --destdir=/tmp
   [...]
   Creating /usr/local/share/doc/foo-1/man1 (and its parents)
   Setup: /usr/local/share/doc: createDirectory: permission denied
 (Permission denied)
   Test failed!
 }}}

 In case my dummy repo goes away, it just contains the two files I have
 attached to this ticket, Setup.hs and foo.cabal.  The test it runs is

 {{{
 set -ex; ghc -Wall --make Setup; ./Setup configure; ./Setup build; ./Setup
 copy --verbose --destdir=/tmp
 }}}
