安装*后*更改 macports 安装目录
我在一台计算机上安装了 macports，我希望将整个 /opt 树复制到另一台计算机。除了，在新计算机上（都是带有 Lion 的 Intel Mac，所以我希望避免重新编译所有软件包）我有一个额外的硬盘，所以我想在 /Volumes/extradrive/opt 上安装 macports
我可以复制 macports从旧计算机转移到新计算机，然后在某处更改目录路径？我猜不会，因为所有软件都已编译为 /opt。如果是这样，我可以轻松地在新计算机上重新创建整个 macports 吗？
I have macports installed on one computer, and I was hoping to just copy the entire /opt tree to another computer. Except, on the new computer (both are Intel Macs with Lion, so I am hoping to avoid recompiling all the packages) I have an extra hard disk, so I want to install macports on /Volumes/extradrive/opt
Can I copy the macports tree over from the old computer to the new computer and then change the directory path somewhere? I am guessing not, because all the software has been compiled expecting /opt. If so, can I recreate the entire macports on the new computer easily?

是的，可以在两台计算机上维护一个 MacPorts
/opt目录，并在/opt之外进行一次安装，前提是它们都运行相同版本的 OSX 并且代码。我在自己的机器上执行相同任务的快速而肮脏的方法是：其中
$macports_host_machine是安装 MacPorts 的机器（在/opt/中）。现在，将/Volumes/extradrive/opt链接到/opt：我还执行此附加步骤
来更改符号链接的所有权和权限。
之后，我仅在
$macports_host_machine上维护/opt目录，并定期与所有其他计算机（运行相同版本的 OSX 和 XCode）进行 rsync。前面的说明是假设 MacPorts 安装在
$macports_host_machine上的/opt中，如果 MacPorts 安装在其他非标准位置，则应替换/ opt与$macports_host_machine上的安装路径无关Yes, it is possible to maintain a single MacPorts
/optdirectory on two machines and have one installation outside of/opt, if they are both running the same version of OSX and XCode. The quick and dirty way that I do the same task on my own machines is:where
$macports_host_machineis the machine on which MacPorts is installed (in/opt/). Now, link/Volumes/extradrive/optto/opt:I also perform this additional step
to change ownership and permissions of the symbolic link.
After that, I maintain the
/optdirectory on only$macports_host_machineand rsync with all of my other machines (running the same version of OSX and XCode) periodically.The previous instructions were written assuming that MacPorts was installed in
/opton$macports_host_machine, if MacPorts was installed in some other non-standard location, you should replace/optwith whatever the installation path is on$macports_host_machine
