Did you run build-all before that?  I've noticed recently that some 
dependencies may be missing, so trying to run the regression tests 
directly may not build what it needs automatically.

As far as the original bug goes, it works fine here on Ubuntu 14.04 with 
Python 2.7.6, with or without the apparently pointless new patch, so the 
Python version isn't the issue.  A useful thing to do after the necessary 
builds is:

        strace -e trace=open python -m gps.packet

When I was fixing previous trouble in this area, I noticed that it would 
prefer the old packet.so file if it was present, so I added code to remove 
it.  But looking at the trace, it seems that there are actually three 
things it looks for before finally looking for the right thing:

open("/home/fw/gpsd/gps/packet.x86_64-linux-gnu.so", O_RDONLY) = -1 ENOENT (No 
such file or directory)
open("/home/fw/gpsd/gps/packet.so", O_RDONLY) = -1 ENOENT (No such file or 
directory)
open("/home/fw/gpsd/gps/packetmodule.so", O_RDONLY) = -1 ENOENT (No such file 
or directory)
open("/home/fw/gpsd/gps/packet.py", O_RDONLY) = 3

So perhaps one of those is there.  Otherwise, it should be possible from 
the trace to figure out exactly what it's looking for.
