Or let request the buildfarm to generate the missing package. 
Perhaps throwing some symlinks will also help.

Whats speaks against respecting FHS ? 

Or why not using the environment ? 
Many, many applications can read their config or data location from 
environment variables, i.e. mutt, procmail, postgresql, ...

Ah ?
where's the relation between pathes given by --bindir, --libdir, --sysconfdir
and --localstatedir ?

cant the API be just getenv() ?

No, running the binary from somewhere is now problem, but expecting the
data being somewhere else than defined by the configure options (defaulting
to FHS) or under the homedir, but instead somewhere relative to the
binary is a problem for me. Perhaps you decide to move some binaries to 
a different directory and throw some symlinks (i.e. for splitting to 
multiple partions or even network installs), then you'll ride into trouble.

Why not ?
BTW: it doesnt necessarily need to be FHS, but something similar, which 
splits the directory tree into several semantic parts.
(along those borders which are defined by --sysconfdir & friends)

Feeding up glib with dozens of hacks which only make sense on some 
dying platform is also not productive, since the more glib gets inflated, 
the more people will run away from it.

Perhaps a separate library can provide these features, perhaps this can
also do some more general path/location handling stuff, but glib itself
should not grow anymore, if not really really necessary.
