[Image-SIG] PIL error with encoder

[Dhruv Majumdar]

Hi Fredrik,

>>> import _imaging; print _imaging.__file__
/usr/local/lib/python2.7/site-packages/PIL/_imaging.so


Here's a dump of the complete error in case it helps;

[root at acroplia-1 audioprocessing]# /usr/local/bin/python wav2png.py

rawmode)])
  File "/usr/local/lib/python2.7/site-packages/PIL/ImageFile.py", line 481,
in _save
    e = Image._getencoder(im.mode, e, a, im.encoderconfig)

    raise IOError("encoder %s not available" % encoder_name)
IOError: encoder zip not available
