Python Image Lib Problems

[Mark Conway Wirt]

I've recently build the Python Imaging Library (PIL) and installed it,
but I'm having problems actually getting it to work.  The examples
from the documentation  -- even the simple ones -- produce copious
errors.  For example:

>>> import Image
>>> im = Image.open("lena.ppm")
>>> im.show()
Traceback (innermost last):
  File "<stdin>", line 1, in ?
  File "/usr/local/lib/python1.5/site-packages/PIL/Image.py", line 694, in 
    show _showxv(self, title, command)
  File "/usr/local/lib/python1.5/site-packages/PIL/Image.py", line 974, in 
    _showxv
    file = self._dump(format=format)
  File "/usr/local/lib/python1.5/site-packages/PIL/Image.py", line 311, in 
    _dump
    file = file + "." + format
TypeError: illegal argument type for built-in operation

..or...

>>> import Image, ImageDraw
>>> im = Image.open("lena.ppm")
>>> draw = ImageDraw.Draw(im)
>>> draw.line((0,0), im.size, fill=128)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
TypeError: keyword parameter redefined
>>> 

Am I missing something obvious?  I'm new to python programming, and
finding these errors a bit confusing.

Thanks in advance.  I'm using 1.5.2 on a FreeBSD 3 box, if that's
important.
