Uhm, this sucks.

But the fix should be easy: the calls to
udev_monitor_filter_add_match_tag() just need to be skipped if they are
not available, as they are an optimization only. 

I'll look into prepping a patch that adds an autoconf check for the
call, and ifdefs it out if it isn't found. I don't have RHEL around, can
I get you guys to test this patch for me then?
