Description

The data files in .../qpid-python/python/qpid/specs (i.e. amqp-0-10.dtd, amqp-0-8.xml, amqp-0-9.xml) are accessed using a base path of _file_, which is not available if byte compiled into a py2exe (or pyInstaller) executable. The patch below works around this issue.

I thought this might be useful for others ...
