For the last week or so, there have been packages in the "world" distribution list which previously installed fine which currently do not, these include ruby-gdkpixbuf2, ruby-pango, ruby-gtk2, ruby-gnomecanvas2, ruby-gnome2 and ruby-libglade2 (this is on an x86 system). My reading of the bug reports suggest that this is a problem with the ruby/gentoo config scripts. If so, ok fine, then pull them from the "world" distribution until such scripts/ebuilds/patches are available. Please do not leave them in the world distribution list when they are known to be defective. It appears that there may be some oversight/direction lacking with respect to what makes up the QA with respect to distributed (e.g. "approved") packages which have known problems.
For people who attempt to update their systems on a nightly basis and provide feedback to the Gentoo developers, this can be an annoying situation (it may require the expansion/contraction of scripts which enable/disable nightly builds). I understand if there is a problem with the upstream source which may take months to fix for the bug reports to percolate up and solutions to percolate down, but in the mean time end users should not be subjected to packages known to be problematic (and thus the packages should be pulled from the world distribution list).
