Note that this is now a "g-module" not a gtk-module, gmodule support is
part of the glib package.

Note this this is a build-time dependency on the at-spi package, which
is quite different from a runtime dependency of a library.  The
libraries from the at-spi package which would be needed by KDE
accessibility integration do not, as far as I know, introduce gtk+
dependencies, and they certainly do not need gail.  As was alluded to
before, the GAIL dependency at build time is presently only a sanity
check to make sure the user of at-spi has some sort of accessibility
implementation present.  Personally I don't think the gail dependency in
configure.in is appropriate but some contributors felt strongly
otherwise, and it does help prevent some erroneous bug reports that
might result if builders of at-spi did not notice the dependency when
reading the docs.
