There are 2 versions of PIL, the original one (development stopped) which
is not available on Fedora any more I think, and the new one - pillow -
which requires different form of import. So you can either install newer
version of GRASS (probably 6.4.4 or 7, but you would have to probably
compile it yourself) which has this issue solved or manually fix the line
in the Python code in your grass installation:

 try:
-    import Image as PILImage
+    from PIL import Image as PILImage
     havePILImage = True
 except ImportError:


If you need some more help let us know.
