Hi Nathaniel, thanks for helping out!

The libxml issue is a known problem with homebrew installs. Let me
know if you’re not using homebrew.

To work around it I suggest making sure libxml2 is installed through
homebrew and running this before configure:

    export PKG_CONFIG_PATH="`brew --prefix 
libxml2`/lib/pkgconfig:$PKG_CONFIG_PATH"
