vala for some reason has || ( sys-devel/bison dev-util/byacc dev-util/yacc ) in DEPEND instead of virtual/yacc. The virtual doesn't have byacc in it, but I question why the vala ebuild author would explicitly list byacc.
> I question why the vala ebuild author would explicitly list byacc. Instead of questioning the ebuild author, you could unpack the tarball and read vala's configure.ac: AC_CHECK_PROGS(YACC, 'bison -y' byacc yacc, :) if test "$YACC" = :; then AC_MSG_ERROR([bison not found but required]) fi I suppose we could switch "|| ( sys-devel/bison dev-util/byacc dev-util/yacc )" to "|| ( virtual/yacc dev-util/byacc )", but I am worried about the possibility of other yacc implementations being added to virtual/yacc, when vala only checks specifically for these three cases.
Don't worry, I've been working with yacc (as a user) and I don't see someone suddenly starting a new yacc project :) On the other hand, bison & all should (and most likely already do, like bison) install a symlink to yacc so the test will succeed here, whatever is installed.
