Meld on OS X 10.7 not working?

Question

I install meld on Mac OS using the port.

He downloaded all the dependencies and said that everything was fine:

Staging meld into destroot Installing meld @1.5.3_0 Activating meld @1.5.3_0 Cleaning meld Updating database of binaries: 100.0% Scanning binaries for linking errors: 100.0% No broken files found. 

but when I ran:

 [18:28:24]~$ meld 

Traceback (last last call):

 File "/opt/local/bin/meld", line 75, in <module> locale.setlocale(locale.LC_ALL,'') File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/locale.py", line 539, in setlocale return _setlocale(category, locale) locale.Error: unsupported locale setting 

what is the problem and how to deal with it?

Answer 1

Installation

 export LANG=C; export LC_ALL=C 

fixed the problem and let meld run.
