New issue 1139 by janne.t.harko...@gmail.com: Relative imports found from  
PYTHONPATH do not work
http://code.google.com/p/robotframework/issues/detail?id=1139

having following files

test.txt
lib/--
        | Lib.py

and import like this in test.txt:
*** Settings ***
Lib.py

executing robot like this:

import sys
import robot
sys.path.append('lib')

robot.run('test.txt')

fails with following error message:

Error in file '/Users/jth/code/robotframework/tmp/test.txt' in  
table 'Settings': Importing test library 'lib/Lib.py' failed: ImportError:  
Import by filename is not supported.

Same thing happens if a variable file is imported the same way
