r23157 removed the {boost,boost-build}1-.35 masks in profiles/package.mask. Now boost-1.35.0-r1 can not be emerged due to the missing appropriate boost-build: $ emerge -pv boost These are the packages that would be merged, in order: Calculating dependencies... done! emerge: there are no ebuilds to satisfy ">=dev-util/boost-build-1.35.0-r1". (dependency required by "dev-libs/boost-1.35.0-r1" [ebuild])
I wasn't able to finish my sync round this morning. It should be in the tree now, sorry for the inconvenience.
