I did an emerge -uD world and had it fail because of this: emerge: there are no ebuilds to satisfy ">=sys-apps/bash-3". (dependency required by "dev-java/blackdown-jdk-1.4.2.03-r12" [ebuild]) Tracking this down, I found this in the latest java-vm-2.eclass: RDEPEND=" =dev-java/java-config-2.0* =dev-java/java-config-1.3* >=sys-apps/bash-3" bash is in app-shells, not sys-apps.
