i'm trying to get gtkradiant running again. in the past i just needed to runs scons and then run the install.py script and everything would be set up. install.py seems to have changed now and when i run it i get this...

usage: install [target directory] [source directory]

...i've tried various things, but with no luck. anyone got any idea what i should be doing here?

Same thing, here. I've managed to build it some time ago but now I just keep getting the same error as you.
Finally I've ended with using .deb package witch lies somewhere in the forum.

I got the same. But install.py is not really needed... radiant and q3map2 is compiled and is laying in a folder. Just start it from there.

i've emailed the gtkradiant devs' mailing list about this, hopefully they'll be able to help me out with this.

thanks to [-z-] i now have a working copy of gtkradiant. he gave me this link for an ubuntu .deb package.
