Comment:
If I change Gtk2hsSetup.hs from:
{{{
#!hs
#if CABAL_VERSION_CHECK(1,10,0)
installedPkgInfo pkg lbi inplace
[packageDb]
#else
installedPkgInfo pkg lbi inplace
packageDb
#endif
}}}
to
{{{
#!hs
#if CABAL_VERSION_CHECK(1,10,0)
installedPkgInfo pkg lbi inplace
(withPackageDB lbi)
#else
installedPkgInfo pkg lbi inplace
packageDb
#endif
}}}
It registers correctly. The packageDb here is defined as:
{{{
#!hs
packageDb = case flagToMaybe (regPackageDB regFlags) of
Just db -> db
Nothing -> registrationPackageDB (withPackageDB lbi)
}}}
In Distribution\Simple\Register.hs it has:
{{{
#!hs
-- FIXME: there's really no guarantee this will work.
-- registering into a totally different db stack can
-- fail if dependencies cannot be satisfied.
packageDbs = nub $ withPackageDB lbi
++ maybeToList (flagToMaybe (regPackageDB regFlags))
}}}
Anyway, it appears that the issue is with Gtk2HsSetup.hs and I will close
this and add to a related ticket there
(http://hackage.haskell.org/trac/gtk2hs/ticket/1203).
