NameError in cpm.py from latest svn source code

Hi,

I just updated gnuradio from svn and found some errors while using
cpm.py.
The error is as followed:

"
File “/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/wx/_core.py”,
line 7700, in init
self._BootstrapApp()
File
“/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode/wx/_core.py”,
line 7352, in _BootstrapApp
return core.PyApp__BootstrapApp(*args, **kwargs)
File “./test_011.py”, line 172, in OnInit
mod.add_options(expert_grp)
File
“/usr/local/lib/python2.4/site-packages/gnuradio/blksimpl/cpm.py”,
line 223, in add_options
parser.add_option("", “–param”, type=“float”, default=_def_param,
NameError: global name ‘_def_param’ is not defined
"

Whereas gdb gives following error and there is no stack in the gdb:
Program terminated with signal SIGHUP, Hangup.

Can someone suggest the solution to this problem? Thanks in advance.
