Hi guys!

I couldn't run a QT GUI RANGE block in grc. Any of its widget (Counter, Slider, etc.) causes an error:

Traceback (most recent call last):
  File "/home/goodman/top_block.py", line 16, in <module>
    import PyQt4.Qwt5 as Qwt
  File "/usr/lib64/python2.7/site-packages/PyQt4/Qwt5/__init__.py", line 32, in <module>
    from Qwt import *
ImportError: /usr/lib64/python2.7/site-packages/PyQt4/Qwt5/Qwt.so: undefined symbol: _ZTI8QwtWheel

>>> Done
Anyway, all other QT GUI Widgets (Chooser, Check Box, etc)  works fine.
All of QT Instrumentation (Frequency Sink, Waterfall Sink, etc) runs too.

A Qwt.so is on the right place. _ZTI8QwtWheel symbol is absent in lib of course.

System  Slackware_14_64
~$ uname --all
Linux home 3.2.29 #2 SMP Mon Sep 17 14:19:22 CDT 2012 x86_64 AMD Turion(tm) II Dual-Core Mobile M500 AuthenticAMD GNU/Linux

Gnuradio and all that it need are built from sources.
GCC 4.7.1

Any ideas, please!

73!  Andrey.
