It *might be* the line endings.

If I have "DOS" style line endings in a file then on Linux I see:

vagrant@precise64:/vagrant$ cat try.rb
#!/usr/bin/env ruby

puts "Hello"
vagrant@precise64:/vagrant$ ls -l try.rb
-rwxrwxr-x 1 vagrant vagrant 37 Jun 29 23:38 try.rb
vagrant@precise64:/vagrant$ ./try.rb
: No such file or directory

On my Mac trying the same thing I get a more obvious clue:

ratdog:vagrant_book_example mike$ ./try.rb
env: ruby\r: No such file or directory

Which tells me there is a \r at the end of the #! line. I often use the file command to check, again on Linux:

vagrant@precise64:/vagrant$ file try.rb
try.rb: a ruby\015 script, ASCII text executable, with CRLF line terminators

The CRLF is one give-away.

Hope this helps,

Mike
