Xlib.h not found when building graphviz on Mac OS X 10.8 (Mountain Lion)
When using homebrew to install graphviz, the script gets to the point of "Making install in tkstubs" and then throws the following fatal error: In file included from tkStubLib.c:15: /usr/include/tk.h:78:11: fatal error: 'X11/Xlib.h' file not found #include <X11/Xlib.h> I have installed XQuartz as X11 has been dropped in Mountain Lion, but I'm unsure if it is installed correctly. The location of Xlib.h is: /opt/X11/include/X11/Xlib.h There are also two symlinks to /opt/X11, they are: /usr/X11 /usr/X11R6 Does this look like the correct setup to you? I've never dealt with X11 or XQuartz until
