Hello,

I've downloaded on my macbook pro running os 10.6.4 the disk image 
spyder-2.2.1.dmg and installed Spyder, after having installed Python2.7.5, 
Qt4.7.4, and PyQt4.10, which run correctly together. Launching Spyder 
results in the error "Please check Spyder installation requirements : PyQt4 
4.4+ (or Pyside1.1.1+) is required" and the log console messages :

I'm new to python and to the machinery of mac applications, but I noticed 
that the problem may comes from the importation of 'qt', as, when adding in 
'spyderlib.spyder.py' module a test in the try section (line  43 to 49) for 
the import of 'qt' from 'Ipython.external', it shows the failure of the 
import, as well as when setting a similar test when trying to import 'qt' 
from 'spyderlib' in the check_qt part of  'spyderlib.requirements.py'.

Has someone alaready met this problems, and if so, are there explanations 
and perhaps workarounds ?

Having downloaded the Spyder-2.2.3 source, it works fine, either in the 
bootstrap mode, or after installing it, and I would be quite happy with 
these way of running Spyder, but I would also find nice to launch Spyder as 
a mac application.

Many thanks for those who have developed this nice and efficient 
application.
