我正在尝试使用32位Python 2.7(来自python.org)和来自MacPorts的cairo 1.10.2在我的OS X 10.5上安装PyCairo(来自tarball源码).所以我正在安装“py2cairo”.当我运行python ./waf configure时,我明白了

Checking for 'cairo' >= 1.10.0           : not found 

我这里有cairo文件……

$ls /opt/local/include/cairo
cairo-deprecated.h          cairo-gobject.h             cairo-script-interpreter.h  cairo-tee.h                 cairo-xlib-xrender.h        cairo.h
cairo-features.h            cairo-pdf.h                 cairo-script.h              cairo-version.h             cairo-xlib.h
cairo-ft.h                  cairo-ps.h                  cairo-svg.h                 cairo-xcb.h                 cairo-xml.h
$ls /opt/local/lib/cairo
cairo-fdr.0.so*         cairo-fdr.la*           cairo-sphinx.0.so*      cairo-sphinx.la*        libcairo-trace.0.dylib* libcairo-trace.dylib@
cairo-fdr.a             cairo-fdr.so@           cairo-sphinx.a          cairo-sphinx.so@        libcairo-trace.a        libcairo-trace.la*

但是我将哪个目录传递给哪个参数？这些在指定cairo库时看起来不相关：

$python ./waf --help
  ./options()
waf [commands] [options]

Main commands (example: ./waf build -j4)
