sbt 1.0.2 has been released. See http://www.scala-sbt.org/download.html
Thank you for the bump request. You can help the maintainer with further information: Does a simple bump [1] work on your system? Chances are high, because a first look on the bump revealed only small changes. [1] https://wiki.gentoo.org/wiki/Custom_repository#Simple_version_bump_of_an_ebuild_in_the_local_overlay
Simply bumping the ebuild doesn't help, as they don't seem to publish sbt-bin to bintray.com anymore. SRC_URI has to be changed to github as follows. SRC_URI="https://github.com/sbt/sbt/releases/download/v${PV}/${PN/-bin}-${PV}.tgz" Then everything works. Meanwhile 1.0.4 is already out.
sbt 1.1.1 is available
sbt-1.1.4 is available. Works fine with renamed ebuild with SRC_URI="https://github.com/sbt/sbt/releases/download/v${PV}/${PN/-bin}-${PV}.tgz"
