Subject: [PATCH] 00187-add-RPATH-to-pyexpat.patch

00187 #
Add an explicit RPATH to pyexpat.so pointing at the directory
containing the system expat (which has the extra XML_SetHashSalt
symbol), to avoid an ImportError with a link error if there's an
LD_LIBRARY_PATH containing a "vanilla" build of expat (without the
symbol)
