我尝试使用以下命令安装和运行 ddd：
brew install libtool
brew link lesstif
brew install ddd
并在尝试运行 ddd 时收到以下错误消息：
cd@new-host:~$ ddd

以下是我从酿造医生那里得到的输出：
Warning: Some directories in /usr/local/share/man aren't writable. This can happen if you "sudo make install" software that isn't managed by Homebrew. If a brew tries to add locale information to one of these directories, then the install will fail during the link step. You should probably chown them:
/usr/local/share/man/de
/usr/local/share/man/de/man1
/usr/local/share/man/mann

Warning: /usr/bin occurs before /usr/local/bin This means that system-provided programs will be used instead of those provided by Homebrew. The following tools exist at both paths:

Consider setting your PATH so that /usr/local/bin occurs before /usr/bin. Here is a one-liner:
echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile
这些酿酒医生的警告是我实际上应该尝试纠正的吗？ 我所有其他 brew 安装程序都很好，所以有点不愿意开始处理这些文件。谢谢！
编辑：在macOS 10.14.4上，我收到此错误：
Jamess-MacBook-Air:haskell-usaco james$ ddd
Error: Unresolved inheritance operation
Xt error (Unresolved inheritance operation).
Oops! You have found a bug in DDD.
If you can reproduce this bug, please send a bug report
to <ddd@gnu.org>, giving a subject like
DDD 3.3.12 (i386-apple-darwin18.0.0) gets Xt error
使用 LLDB 启动 DDD 会打印出以下错误消息：
XIO: fatal IO error 35 (Resource temporarily unavailable) on X server "/private/tmp/com.apple.launchd.cxF3NWNYqR/org.macosforge.xquartz:0"
after 5 requests (5 known processed) with 0 events remaining
X11是从Homebrew和XQuartz网站安装的。
所以我认为Mac OS X 10.7.5.附带XQuartz(安装中只有10.8及更高版本(。
以下是最终对我有用的方法：
未酿造的dylibs，头文件，.pc文件和静态库是由非自制安装放置在那里的，因此我使用以下命令卸载了R：
rm -rf /Library/Frameworks/R.framework /Applications/R.app
/usr/bin/R /usr/bin/Rscript
然后我卸载了 ddd，取消了链接的 lesstif，并卸载了 lesstif：
brew uninstall ddd
brew unlink lesstif
brew uninstall lesstif
接下来，我安装了 tcl-tk：
brew tap homebrew/dupes
brew install tcl-tk
然后我用brew安装从源代码构建了lesstif：
brew install --build-from-source lesstif
我重新链接了lesstif：
brew unlink lesstif && brew link lesstif
最后，我安装了 ddd：
brew install ddd
它奏效了！我不确定这些步骤中的哪一个是关键步骤，但我猜是：
brew install --build-from-source lesstif
我仍然不确定这两者有什么不同：
brew install --build-from-source lesstif
brew install lesstif
我还查找了以下目录和文件：
/opt/X11/lib/libSM.6.dylib exist
但它们在我的电脑上不存在。
@new-host:~$ cd ~
@new-host:~$ cd /opt
-bash: cd: /opt: No such file or directory
相反，我在这里找到了 X11 文件：
@new-host:/usr/X11$ cd ~
@new-host:~$ cd /usr/X11/lib
@new-host:/usr/X11/lib$ ls
...
libSM.6.dylib
...
我想我可以使用某种符号链接来解决这个问题，但不完全确定。
最后，那些未编写的dylibs，头文件，.pc文件和静态库由R的非自制安装放置在那里。但我不确定实际上有任何方法可以安全地删除它们以消除酿造医生的警告。(我可能不得不和他们住在一起(。
R 安装由三个 Apple 软件包组成：
org.r-project.R.x86_64.fw.pkg
org.r-project.R.x86_64.GUI.pkg
org.r-project.x86_64.tcltk.x11
根据 R 网站 (http://cran.r-project.org/doc/manuals/r-release/R-admin.html#Uninstalling-under-OS-X(：如果您希望 Apple 安装程序忘记软件包而不删除其文件(在并行安装多个 R 版本时对 R 框架很有用(，或者在删除文件后，可以使用 pkgutil --unlink(Lion 或更高版本不支持(删除其文件或pkgutil --forget
卸载 Tcl/Tk 组件(安装在 /usr/local 下(并不简单。您可以通过以下方式列出它在终端中安装的文件
pkgutil --files org.r-project.x86_64.tcltk.x11
对我来说有点太可怕了，无法解决这种删除问题，因此将接受brew doctor警告。 很高兴ddd终于奏效了。
你需要安装 XQuartz 才能在/opt/lib 中获取这些 X 库。
