See the proposal for relative paths in installed package descriptions:
http://www.haskell.org/pipermail/libraries/2009-May/011772.html
Basically it amounts to replacing ghc's current `$topdir` and
`$httptopdir` with variables that are interpreted relative to the package
db file itself rather than relative to where ghc is installed (though for
the global package db these coincide).
The open question is how tools discover the location of the package dbs.
The proposed spec extension does not specify this, but perhaps it should
specify an extension to (the hypothetical) `hc-pkg` system to discover the
default set of package dbs and their paths.
