Hi Paul.  We us a program called "env" with the argument "ruby" to
find ruby in the path and run the script with whatever ruby was found
in the path.  By the look of the error message, the env program can't
find ruby on your system for some reason.  I ran it on my Mac with a
bogus program name and you can see that the output is similar:

tashi-delek:~ chadfowler$ /usr/bin/env hello_paul
env: hello_paul: No such file or directory

Now if I run env manually with "ruby" as the parameter, I see:

tashi-delek:~ chadfowler$ env ruby -e 'puts "hello"'
hello

It appears that the "env" program doesn't deal with shell aliases (not
surprising):

tashi-delek:~ chadfowler$ alias myruby=/usr/local/bin/ruby
tashi-delek:~ chadfowler$ myruby -v
ruby 1.9.0 (2004-04-30) [powerpc-darwin]
tashi-delek:~ chadfowler$ /usr/bin/env myruby
env: myruby: No such file or directory

Can you try changing the first line of your "gem" script to look like:
#!/usr/local/bin/ruby18

Alternatively, you could create a symbolic link to your ruby
interpreter and call it "ruby" instead of using the aliases:
ln -s /usr/local/bin/ruby18 /usr/local/bin/ruby
