"IOError: zip zip недоступен": Ubuntu Python PIL

Я пытаюсь получить образец heatmap.py, запускаемый из: http://jjguy.com/heatmap/

#image.py
import heatmap
import random

if __name__ == "__main__":    
    pts = []
    for x in range(400):
        pts.append((random.random(), random.random() ))

    print "Processing %d points..." % len(pts)

    hm = heatmap.Heatmap()
    img = hm.heatmap(pts)
    img.save("classic.png")

и я получаю эту ошибку:

Processing 400 points...
Traceback (most recent call last):
  File "/home/ec2usr/workspace/image/image.py", line 14, in <module>
    img.save("classic.png")
  File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1437, in save
    save_handler(self, fp, filename)
  File "/usr/local/lib/python2.7/dist-packages/PIL/PngImagePlugin.py", line 572, in _save
    ImageFile._save(im, _idat(fp, chunk), [("zip", (0,0)+im.size, 0, rawmode)])
  File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 481, in _save
    e = Image._getencoder(im.mode, e, a, im.encoderconfig)
  File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 399, in _getencoder
    raise IOError("encoder %s not available" % encoder_name)
IOError: encoder zip not available

Отключение Eclipse в системе Ubuntu 12 (64 бит) с Python 2.7.

Я нахожу libz.so как в /usr/lib, так и в/usr/lib/x86_64-linux-gnu/просто отлично. Я пробовал эти решения уже безрезультатно:

PIL говорит, что у него есть "поддержка доступна" но все же дает IOError при сохранении файлов

Я тянул свои волосы за это несколько дней и очень признателен за помощь!
