Both dev-tex/polytable and dev-tex/lazylist are needed to build dev-haskell/lhs2tex. Since I tested dev-haskell/lhs2tex on ppc64 with success, it seems that dev-tex/polytable and dev-tex/lazylist are working on ppc64 as well. We should keyword these with ~ppc64 to enable further testing of dev-haskell/lhs2tex on ppc64.
Thanks a lot! Fixed in CVS.
