Bug Description

This is the content of the _imaging compiled module from Oneiric desktop amd64 [20110624]:

>>> import _imaging
>>> dir(_imaging)
['__doc__', '__file__', '__name__', '__package__', 'bit_decoder', 'blend', 'convert', 'copy', 'crc32', 'draw', 'effect_mandelbrot', 'effect_noise', 'eps_encoder', 'fill', 'fli_decoder', 'font', 'getcodecstatus', 'getcount', 'gif_decoder', 'gif_encoder', 'hex_decoder', 'hex_encoder', 'jpeg_decoder', 'jpeg_encoder', 'jpeglib_version', 'linear_gradient', 'map_buffer', 'msp_decoder', 'new', 'open_ppm', 'outline', 'packbits_decoder', 'path', 'pcd_decoder', 'pcx_decoder', 'pcx_encoder', 'radial_gradient', 'raw_decoder', 'raw_encoder', 'sun_rle_decoder', 'tga_rle_decoder', 'tiff_lzw_decoder', 'wedge', 'xbm_decoder', 'xbm_encoder', 'zip_decoder', 'zip_encoder', 'zlib_version']

And, this is the content after I dist-upgrade:

['__doc__', '__file__', '__name__', '__package__', 'bit_decoder', 'blend', 'convert', 'copy', 'crc32', 'draw', 'effect_mandelbrot', 'effect_noise', 'eps_encoder', 'fill', 'fli_decoder', 'font', 'getcodecstatus', 'getcount', 'gif_decoder', 'gif_encoder', 'hex_decoder', 'hex_encoder', 'linear_gradient', 'map_buffer', 'msp_decoder', 'new', 'open_ppm', 'outline', 'packbits_decoder', 'path', 'pcd_decoder', 'pcx_decoder', 'pcx_encoder', 'radial_gradient', 'raw_decoder', 'raw_encoder', 'sun_rle_decoder', 'tga_rle_decoder', 'tiff_lzw_decoder', 'wedge', 'xbm_decoder', 'xbm_encoder']

Notice how the latter no longer contains the zip encoder and decoder... this is causing some dependent projects to fail building, like Launchpad itself, with the exception: IOError: decoder zip not available

Modifying setup.py to know about the new architecture specific lib directories seems to fix the problem. Here is an example diff where the architecture is hard coded, I'm sure there's precedent in other packages to patch the file properly:

I was right! Multiarch.

Thanks, I'll work on an upload to fix this.
