package-recursiveではビルドした状態でそのまま他のをビルドしに行くのでやっかいな問題がしばしば起る．
⇒ 「ビルド放置問題」
たとえば
同じ種類で異なるバージョンのものをインストールしようとしてコケる

通常既にビルドしたものはUSE_PACKAGE_DEPENDS=yesとしてpackageからインストールしてビルド時間を節約するが，そうするとそのpackageのportもビルドしに行く．
⇒ 「二重ビルド問題」
packageの作成順序がFILOなのでビルド途中でコケると，(2)の方法でビルドした場合，そのpackageがインストールされると，そのpackageが必要とするpackageが無いと言ってコケる．
