A few hours after the 0.8 Beta1 announcement was posted a regression was reported in the package manager due to which you might be seeing an ERROR message while installing:

ERROR: The following packages not found in any catalog: SUNWgnome-print SUNWgnome-print-root

The package manager spkg (SFEspkg) has been fixed, so just re-running  pfexec ./install_belenix -reinit  should automatically pull in the latest package.
