Hi, I've run the attached script to find duplicates of packages from sage-on-gentoo in science. The output was: $ ./find-overlay-dups.sh sci-chemistry/jmol sci-libs/fplll sci-libs/givaro sci-libs/iml sci-libs/m4ri sci-libs/symmetrica sci-mathematics/gap sci-mathematics/polybori What do people think about merging those versions in the science overlay and removing them from sage-on-gentoo (or vice-versa)? Probably in most cases there are additional fixes in sage-on-gentoo that science users could benefit from (or at least should hurt nobody)? Cheers, Thomas -- Thomas Kahle http://dev.gentoo.org/~tomka/
