bison ebuilds starting from 2.5.1 up to 2.6.2 uses non-posix argument to mv that can cause ebuild to fail in install phase when using mv implementations that do not support the argument. Solution: remove -v arguments to mv in bison ebuild Resources: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/mv.html
yeah, i have no idea why that was added
should be all set now in the tree; thanks for the report!
