Essentially, the _core_ problem is that libdirectfb API is even less
stable than the glutton implementation; they change little details in
every minor release (without, at least IIRC, providing preprocessor macros
to allow checking for this). I'd recommend not linking against this library
(few people use it anyway) for the time being, until we've come up with
a fix (which would probably amount to a cross-compiler-breaking piece
of code along the lines of

int main(int argc, char **argv)
{
        printf("%d\n%d\n%d\n", directfb_major_version,
                         directfb_minor_version, directb_patchlevel);
        return 0;
}

...and assigning the results to preprocessor macros in configure.in).

I'll contact the directfb maintainer to point out this issue.
