As your paths begin /opt/local I assume you are using macports
当您的路径开始时 /opt/local 我假设您正在使用macports
If so I think you need to at least do a sudo port selfupdate as the current tiff port depends on /libjpeg.7.dylib.
如果是这样，我认为您至少需要执行 sudo 端口 selfupdate，因为当前的 tiff 端口取决于 /libjpeg.7.dylib。
Possible a complete reinstall is needed if the macports was installed under Leopard or earlier
如果 macports 是在 Leopard 或更早版本下安装的，则可能需要完全重新安装

After you do your
在你做完你的
sudo port selfupdate
don't forget to do a
不要忘记做一个
sudo port upgrade outdated
to upgrade your existing ports. Much better than reinstalling everything :-)
升级您现有的端口。比重新安装所有东西要好得多:-)

On my Leopard machine using macports, libsdl_imagewas looking for this non-installed jpeg lib. The jpeg6bport includes it, but at a different path (/opt/local/lib/jpeg6b/lib/libjpeg.62.dylib). I fixed it by doing
在我使用 macports 的 Leopard 机器上，libsdl_image正在寻找这个未安装的 jpeg 库。所述jpeg6b端口包括它，但在不同的路径（/opt/local/lib/jpeg6b/lib/libjpeg.62.dylib）。我通过做修复了它
port selfupdate
port install libsdl_image
which upgraded libsdl_image from 1.2.8_0 to 1.2.10_2 and made the problem go away.
它将 libsdl_image 从 1.2.8_0 升级到 1.2.10_2 并使问题消失。

I had the same problem. I have never runned anything else than Snow Leopard. I have tried all kind of stuff and used about 10 hours trying to fix this problem, but with no success.
我有同样的问题。除了雪豹，我从来没有跑过其他任何东西。我尝试了各种方法并用了大约 10 个小时试图解决这个问题，但没有成功。
I ended up removing macports completely and installed it again.
我最终完全删除了 macports 并重新安装了它。
This is what I did:
这就是我所做的：
First I got a list of all my installed ports:
首先，我得到了所有已安装端口的列表：
> port installed
Then I uninstalled everything:
然后我卸载了所有东西：
> sudo port -f uninstall installed
And installed macports again: macportsand installed all my packages again.
并再次安装 macports：macports并再次安装我的所有软件包。
It was rather tedious, but it did the trick.
这是相当乏味的，但它做到了。
