+		# 1. remove the https://dev.gentoo.org/~gienah/snapshots/${P}-ivy2-deps.tar.bz2
+		# https://dev.gentoo.org/~gienah/snapshots/${P}-sbt-deps.tar.bz2 and
+		# https://dev.gentoo.org/~gienah/snapshots/${P}-test-deps.tar.bz2 from SRC_URI
+		# 2. Comment the sbt publishLocal line in src_compile.
+		# 3. try:
+		# FEATURES='noclean -test' emerge -v dev-java/sbt
+		# It should fail in src_install since the sbt publishLocal is not done.
+		# Check if it downloads more stuff in
+		# src_compile to ${WORKDIR}/.ivy2 and ${WORKDIR}/.sbt.
+		# 4. If some of the downloads fail, it might be necessary to run the sbt compile
+		# again manually to obtain all the dependencies, if so (with jdk 1.6):
+		# cd to ${S}
+		# export EROOT=/
+		# export WORKDIR='/var/tmp/portage/dev-java/sbt-0.13.8/work'
+		# export SV="2.10"
+		# export B_P=sbt-0.13.7
+		# export PATH="/usr/share/scala-${SV}/bin:${WORKDIR}/${B_P}:${PATH}"
+		# sbt compile
+		# cd ${WORKDIR}
+		# find .ivy2 .sbt -uid 0 -exec chown portage:portage {} \;
+		# 5. cd ${WORKDIR}
+		# tar -cjf sbt-0.13.8-ivy2-deps.tar.bz2 .ivy2
+		# tar -cjf sbt-0.13.8-sbt-deps.tar.bz2 .sbt
+		# 6. It downloads more dependencies for src_test, however the presence of some of these may cause
+		# the src_compile to fail.  So download them seperately as root so we can identify the
+		# additional files.  Note: src_test creates some files in ${WORKDIR}/.m2 which are can
+		# hopefully be ignored. As root:
+		# cd ${S}
+		# sbt test
+		# cd ${WORKDIR}
+		# find .ivy2 .sbt -uid 0 -print
+		# Then add those files to sbt-0.13.8-ivy2-test-deps.tar.bz2 except the files in the directories
+		# .ivy2/local
+		# .ivy2/cache/org.scala-sbt
+		# Something like:
+		# tar --owner=portage --group=portage -cjf sbt-0.13.8-test-deps.tar.bz2 <list of files as described above>
