在mac os上使用octave绘图时发现：

dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib

出错信息类似：

dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib
  Referenced from: /usr/X11R6/lib/libfontconfig.1.dylib
  Reason: Incompatible library version: libfontconfig.1.dylib requires version 13.0.0 or later, but libfreetype.6.dylib provides version 10.0.0

error: you must have gnuplot installed to display graphics; if you have gnuplot installed in a non-standard location, see the 'gnuplot_binary' function

解决方案在http://stackoverflow.com/questions/4175411/plotting-with-octave-after-most-recent-mac-osx-update 上找到

在mac os的以下文件中

/Applications/Gnuplot.app/Contents/Resources/bin/gnuplot
找到DYLD_LIBRARY_PATH替换为DYLD_FALLBACK_LIBRARY_PATH，一共有4处，全部替换。

然后OK。
