[GRASS-user] Error with GRASS 6.4.1 on CentOS 5

Hello,

I just built and installed GRASS 6.4.1 on CentOS 5.6 and I get the
following error (GRASS 6.4.0 was working fine):

[mbaudier@alma ~]$ grass64
Cleaning up temporary files ...
Starting GRASS ...
Traceback (most recent call last):
  File "/usr/lib64/grass-6.4.1/etc/wxpython/gis_set.py", line 38, in ?
    import gui_modules.goutput
  File "/usr/lib64/grass-6.4.1/etc/wxpython/gui_modules/goutput.py",
line 39, in ?
    import prompt
  File "/usr/lib64/grass-6.4.1/etc/wxpython/gui_modules/prompt.py", line 864
    ignoredDelimiter = ignoredDelimiter if ignoredDelimiter is not None else ''
                                         ^
SyntaxError: invalid syntax
Error in GUI startup. If necessary, please
report this error to the GRASS developers.
Switching to text mode now.

Any idea of what could cause this?

On CentOS 5 (and RHEL 5 and Scientific Linux 5), the python version is 2.4.3.
We use wxPython from the EPEL repository (version 2.8.11).

Thanks in advance for your help!

Cheers,

Mathieu
