看起来端口一开始就没有处于干净的状态？

我在防火墙后面，可能不允许rsync。

答案1
您的 Portfile 似乎已损坏：您的 openssl 端口没有校验和變數集。
这清洁--全部操作没有任何帮助，因为它清理了 distfile（正在构建的端口的实际档案）和工作目录，而不是 Portfile。
你可以通过运行以下命令检查当前 Portfile 中是否有校验和设置：
port cat openssl | grep checksums ; echo $?
A1输出意味着 Portfile 已损坏。
恢复文件的最简单方法是删除它，然后重新同步，在 rsync 或 svn 上（我不确定单个 tarball）。因此，在 sources.conf 中切换回 svn，即恢复文件：///输入并运行：
sudo port -d sync; sudo rm $(port dir openssl)/Portfile; sudo port -d sync
中的错误编辑2意味着你的 port 命令不知道 portfile 中使用的程序，也就是说它已经过时了。我不确定为什么自我更新没有更新。
