Packages are built against particular versions of other packages, e.g.:

$ ../compiler/stage2/ghc-inplace --show-iface unix/dist/build/System/Posix/Directory.hi | grep "package dependencies"
package dependencies: base directory-1.0 filepath-1.0 old-locale-1.0

so it will always point to the right docs.

I've changed it to include the version in STABLE, and will push to HEAD
once I've validated.


Thanks
