and likewise for poppler.override.
I do have that header (/sw/include/poppler/glib/poppler.h) and I can see the appropriate -I/sw/include/poppler/glib for it (as detected from configure's pkg-config check of poppler-glib, where poppler-0.22.1's poppler-glib.pc.in has: Cflags: -I${includedir}/poppler/glib.
So there's the problem: poppler publishes up through the glib/ subdir that contains poppler.h but pypoppler also includes that subdir in the #include. Solution is to #include <poppler.h> rather than <glib/poppler.h>
