例如，本地保存了很多旧distfiles，现在下载了新的ports代码
ports里面 firefox 版本是20了，build过程会自动下载新的distfiles，所以distfiles 中的firefox 15就没有存在的必要了。

有啥命令，自动清除ports不再需要的distfiles文件？

搞定，自言自语吧


remove old distfiles no longer associated with ports?
how to auto clean old distfiles no longer associated with new ports source.

first, let dpb auto generate file /usr/ports/distfiles/history
# /usr/ports/infrastructure/bin/dpb -D HISTORY_ONLY

second, let clean-old-distfiles do it, clean-old-distfiles depends on history log that records obsolete distfiles.
# /usr/ports/infrastructure/bin/clean-old-distfiles
