Rubyscript2exe on osx error

Hi,

I tried to do an executable of a simple script using rubyscript2exe on
OSX, ruby 1.8 and that what I got when I run the created application:

unknown-00-17-f2-ed-65-fe:~ kwicher$ /Users/kwicher/Documents/Ruby/
rubyscript2exe/wxruby1_darwin; exit
wxruby1_darwin: Couldn't write file (BLOCKCOPYFROMGZ).
logout
[Process completed]

Any idea what is wrong?
