It may come from a broken version of zypper/libzypp in the chroot, which do not see noarch packages. This problem was reported with zypper 1.5.3 and libzypp 8.12.1. We suggest you to update your zypper version to 1.6+. For convenience, we backported zypper 1.6.15 and libzypp 9.10.2 to Meego 1.2.0.
First add our repository to your chroot's zypper configuration file:
obslight addRepoInChRoot --projectLocalName $ProjectName --url http://repo.pub.meego.com/home:/fvennetier:/zypper-backport/MeeGo_1.2.0_standard/ --alias "Zypper_1.6.15_backport"
Then go to the chroot and update zypper:
obslight goToChRoot --projectLocalName $ProjectName # zypper update zypper # exit
