I do seem to have pkg-config installed:

    % which pkg-config
    /usr/bin/pkg-config
    % pkg-config --version
    0.26

Is that the same tool we are talking about? pkg-config, I thought,
was a tool initially from the Gtk+ project. I would seem strange
that aclocal would depend on it.

Is there a special command to run for it to work? I used the exact
same aclocal version, compiled from sources and without modification,
and I still see that pkg.m4 disappears...

Thanks,
