[Gnuplot-py-users] gnuplot problem - MacOSX

[Peter V. <pvi...@gm...>]

After installation of Gnuplot.py, I'm getting the following:
>> gnuplot
dyld: Library not loaded: /opt/local/lib/libXau.6.dylib
  Referenced from: /opt/local/lib/libgd.2.dylib
  Reason: no suitable image found.  Did find:
/opt/local/lib/libXau.6.dylib: mach-o, but wrong architecture
Trace/BPT trap

Any help would be most appreciated.
Thanks.
