Rubyscript2exe with tk and extlib help

I’m having issues running an exe created with rubyscript2exe.

ruby rubyscript2exe-0.5.3.rb fwcatalog.rb --rubyscript2exe-tk

It will make the .exe fine, but when running it will bomb out because I
utilize tkextlib/tile which doesn’t seem to be included.

Can anyone help me figure out how to make sure the tkextlib is included
so I can still use tile?
