Yeah, I noticed that too, its on my todo list, its the setup.py python
building part, I need to either make it silent and provide just one:

PYTHON perf.so

message or to ditch using setup.py and do everything directly, which I
may need to do anyway because 'python setup.py --build-base" (or
equivalent, that I haven't found) doesn't work with 'install', just with
'build'.

For now its just a nuisance, not something crucial, but I'll get that
nailed.
