Question about bug #871

[Marcel Pol]

Hello,
I have a question about this bug:
http://bugzilla.xfce.org/show_bug.cgi?id=871

It's about xfprint 4.2.1 and the cups-plugin, where xfprint gives:
** ERROR **: Unable to load printing system module cups_plugin.so

The fix would be to change the Makefile.in and Makefile.am files for
both xfprint4 and xfprint-manager, which need -Wl,-E added to the
LDFlags so they export their symbols to the plugin.
That was exactly what I did, and the xfprint4 works now, but the
xfprint-manager still breaks in the same way.
I'd like to backport the fix for Mandriva 10.2, which has the broken
xfprint-4.2.1. I'd rather have a complete fix/backport then update to
4.2.2, since that's less risky.
So my question is, what's missing from the fix mentioned in the bugreport?

Regards,
Marcel Pol
