The imported module and the main script both reside on the same directory,  
and it is executed from there. sys.path contains '' in this case (not the  
full path). The script changes the current directory (os.chdir) after  
doing other imports and initialization. From now on, importing a module  
 from the original directory doesn't work anymore.
