So I added the following:\n\n$ export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/mingw64/lib/pkgconfig\n\nAfter adding that and running autogen.sh then configure I was able to complete.\n\nI suggest putting a note in README-win32.txt about the environment variables or adding a bash shell script to check the environment variables to see that the proper package locations are there.  Took a bit to just run configure.  \n\nRunning make, well that is a different..
