Qtcore error problem

Dear python users,
I am new to python and now I met a problem. When I try to run a py file, I
got the following error:
 from vacumm.misc.grid.regridding import regrid2d
 File
"/home/xzhang3/usr/local/uvcdat/2.4.1/lib/python2.7/site-packages/vacumm/misc/__init__.py",
line 41, in <module>
 import color
 File
"/home/xzhang3/usr/local/uvcdat/2.4.1/lib/python2.7/site-packages/vacumm/misc/color.py",
line 50, in <module>
 import pylab as P
ImportError:
/home/xzhang3/usr/local/uvcdat/2.4.1/lib/python2.7/site-packages/PyQt4/QtCore.so:
undefined symbol: _ZN7QLocale14scriptToStringENS_6ScriptE
I searched the web and it looks like the problem has something to do with
different versions.
Any idea how to fix the problem ? I am using python 2.7 now.
Really appreciate your ideas and best regards,
Xiao
