Subject: Permission denied when running Ruby script

I think that this question might be due to me lacking some fundamental
linux knowledge but please can someone explain to me what is going on
here.  I have a ruby script that I would like to call via a cron job.  I
have made the necessary adjustments to crontab but i can't get it to
work.  I think that this is because the user is getting a 'permission
denied' message when i try and call the script directly, however, it
works when i call it with a ruby prefix:
e.g.
user@server:ruby test_script.rb
=> script works
user@server:./test_server.rb
=> -bash: ./test_server.rb: Permission denied

The script starts with the shebang line: #!/usr/bin/env ruby

On my development machine, I'm using cygwin and the script works when
called either way:
e.g.
user@dev:ruby test_script.rb
=> script works
user@dev:./test_server.rb
=> script works

Please can someone explain why (on the server) I am getting the
permission denied message?  The same user can successfully run the
script if they call it with the ruby prefix.
