Branden, In current debian ppc sid, when I install the experimental XFree86 4.2.0-0pre1v3 packages since perl 5.80 has been installed I see the following extra warnings (I am assuming these aren't really errors)...
Setting up xfree86-common (4.2.0-0pre1v3.1) ... Filehandle STDIN opened only for output at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 155. Setting up xserver-xfree86 (4.2.0-0pre1v3.1) ... Filehandle STDIN opened only for output at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 155. dexconf: dexconf: existing /etc/X11/XF86Config-4 has missing or half-open debconf region; not writing X server configuration file. Unable to write X server configuration file. You might want to check into those and if they are warnings see if we can suppress them. Thanks. Jack
