Yes, there's a standard idiom for that:

   $:.unshift(File.dirname(__FILE__))

which means: prepend to the list of directories where libraries are  
searched ($:) the directory where this file lives. Note that does not  
assume the directory is the current working directory, since __FILE__  
points to the containing file, no matter how is being evaled.
