我的Mac OS是10.6.8 snow leopard，在wireshark官网下载了OS X 10.6 and later Intel 64-bit .dmg
成功安装。
但是运行的时候wireshark主界面却迟迟不出现，切换到shell下执行wireshark命令，出现如下错误
1、
MacBook-Pro:MacOS $ wireshark
2012-07-16 11:46:23.304 defaults[667:903]
The domain/default pair of (kCFPreferencesAnyApplication, AppleAquaColorVariant) does not exist
2012-07-16 11:46:23.311 defaults[668:903]
The domain/default pair of (kCFPreferencesAnyApplication, AppleHighlightColor) does not exist
dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib
Referenced from: /Applications/Wireshark.app/Contents/Resources/bin/wireshark-bin
Reason: Incompatible library version: wireshark-bin requires version 14.0.0 or later, but libfreetype.6.dylib provides version 13.0.0
2、安装port
需要用port安装freetype的库，但是发现port又没有安装，到这里去下载了http://distfiles.macports.org/MacPorts/MacPorts-1.9.2-10.6-SnowLeopard.dmg，执行安装时，又提示需要安装xcode，原来xcode是苹果公司向开发人员提供的集成开发环境，用于开发Mac OS X和iOS的应用程序。
没办法，花了一个小时的时间去到这里去下载了个http://adcdownload.apple.com/Developer_Tools/xcode_4.2_for_snow_leopard/xcode_4.2_for_snow_leopard.dmg，悲催的是安装时提示错误，如下
不过幸运的是找了个文章--http://stackoverflow.com/questions/10029270/install-xcode-4-2-for-snow-leopard-fails
只要修改系统的日期为2012年3月26日之前即可，成功安装！
接下来终于可以利用sudo port install 安装freetype了，可安装时提示
3、安装freetype
matoMacBook-Pro:zlib-1.2.6 $ sudo port install freetype
---> Computing dependencies for freetype
---> Dependencies to be installed: zlib
---> Staging zlib into destroot
Error: /opt/local/lib/libz.dylib is not in the destroot. Please clean zlib and try again.
Error: Target org.macports.destroot returned: missing /opt/local/lib/libz.dylib in destroot
Error: Failed to install zlib
Log for zlib is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_zlib/main.log
Error: The following dependencies were not installed: zlib
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>
一番google之后，终于让我找到了--http://williamsoo.com/?p=1954&cpage=1#comment-441485
cp /Developer/SDKs/MacOSX10.6.sdk/usr/lib/libz.1.2.3.dylib /opt/local/var/macports/sources/rsync.macports.org/release/ports/archivers/zlib/libz.dylib
然后先单独安装zlib,sudo port install zlib,如果上面那个错误还是出现，可以
sudo port clean --all zlib
再继续
接下来应该就完成了，freetype安装完后，应该就没啥问题了
至此，wireshark就成功安装完毕了！如图，比较难看，不过能用就行啦！
