LibreOffice 编译时依赖需要 graphite， 而graphite的编译又依赖pkg-config。但是不想使用homebrew或者 MacPorts，喜欢下载源码自己编译。pkg-config编译成功后，并且指定了环境变量。
然而make总是报checking for bogus pkg-config... configure: error: yes, from unknown origin. This *will* break the build. Please modify your PATH variable so that $PKG_CONFIG is no longer found by configure scripts.
排查configure.ac发现pkg-config 检查出错后，就退出了。pkg-config的作用主要是为了编译graphite，而graphite是一种“智能字体”系统，专门为处理世界上鲜为人知的语言的复杂性而开发。
然而，对于中文字体可能影响不大。试试忽略这部分功能。于是修改代码如下：
diff --git a/configure.ac b/configure.ac
index 99ccaf54f748..dbb727422dec 100644
--- a/configure.ac
+++ b/configure.ac

注掉后，执行make，果然成功了。
