还是老三样：phpize, ./configure, make && make install
当然是要到你下载的php源码的ext目录中执行。

If you ever happen to want to link against installed librariesin a given directory, LIBDIR, you must either use libtool, andspecify the full pathname of the library, or use the `-LLIBDIR'flag during linking and do at least one of the following: - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable during execution
See any operating system documentation about shared libraries formore information, such as the ld(1) and ld.so(8) manual pages.----------------------------------------------------------------------
