 Hi,

 when the building the Debian package of GHC HEAD, I get this error:

 The problem is that it is calling ghc-pkg at the installed position, where
 it cannot find its libraries.
 `/home/nomeata/dailies/2014-01-31/ghc-7.9.20140130/debian/tmp/usr/lib/ghc/bin
 /ghc-pkg` would also not work, as that refers to absolute paths which are
 not there yet.

 I guess it should continue using the binaries in `inplace/bin` just like
 for `ghc-cabal`. But that alone does not help:

 It would be nice if this can be fixed before 7.8.1, packagers rely on
 `DESTDIR`.
