Just wanted to chime in here and say that the 0.1.11 release works
fine for me in Ubuntu 10.10.  I can't really think of anything that
chirp does that would be system specific with the serial port that
would prevent it from working on OSX.  It opens it, sets the baud
rate, writes a few bytes, reads a few bytes, changes the baud rate,
checks CTS, sets RTS, does some more reads and writes and closes the
port.

CentOS5 also has a fairly old kernel, which would have older drivers,
so that could be another difference.

An interesting patch might be one that changes all the blanket
exception handlers into raise statements if 'debug mode' is turned on.

def print_backtrace():
    a,b,c = sys.exc_info()
    ...

try:
    do some stuff
except:
    if debug:
        print_backtrace()

That way you could normally quiet all the annoying stuff during a
normal run, but you could gather useful information if you are looking
for a bug.  In some cases if you are getting too much junk, the
blanket except handlers might be better turned into a series of
excepts to allow a certain type of exception to pass, while catching
others.
