Please stabilize dev-ruby/libglade-0.16.0-r1. This version was overlooked in a recent attempt to stabilize ruby-gnome2 packages that have been in the tree for quite some time already. Note that currently stable version for amd64 and x86, 0.12.0, does not build anymore on a stable system, bug 216380.
Assuming you really meant dev-ruby/ruby-libglade2-0.16.0-r1 ... Stable on alpha.
amd64/x86 stable
Stable for sparc.
