os.rename() fails in cascadenik-compile.py

[tstucki]

os.rename() apparently won't work if the files are on different filesystems. In my case /tmp is on a different filesystem than /home. Switching to shutli.move() (http://docs.python.org/library/shutil.html#shutil.move) fixed it for me.

This is the error I get:

I am receiving a similar error: log file

My terrible hack solution was to comment out line '49' of cascadenik-compile.py and replace with the a manual call to 'mv':

    #os.rename(tmp_file, dest_file)
    os.system('mv ' + tmp_file + ' ' + dest_file)

Forgot to mention that i am on the mapnik2 branch.

Thanks, Matt

Looks like this was replaced with shutil.move(), which can cross filesystem bounds, some time ago.
