From what I can see, most of the files only pull in one or the other (via some ifdef/elif code blocks), but evidently one of them does not.  I have not been able to track it down, yet - is this something anyone else has encountered?  0.44 seemed to work fine, this seems to be unique to 0.48.

It looks like this might be src/include/types.h including sys/types.h 
and src/include/rbd_types.h, which is including linux/types.h.

Does adding ifdefs to src/include/types.h so it includes linux/types.h 
on linux work?
