the problem is that /usr/bin/env absolutely sucks on linux. -w is not  
only NOT passed as an argument to "ruby", it is considered part of  
ruby (eg "ruby -w") and horks the exec.

If you're tweaking shebang lines JUST FOR YOU, this is fine... but I  
get a bunch of tickets filed against my software that it doesn't work  
for them (mitigated by installing via rubygems). I try to tell them to  
file a bug against their linux distro, but they don't seem to agree  
with me most of the time. :)
