I think you should provide a separate small library just for LZW,
and a stub version of that library with LZW removed. Provide an
lzw_is_available() function to let the software determine if it
can use LZW or not.

Thus, you would have these packages:

imagemagick
imagemagick-dev
lzw1-disabled
lzw1-enabled

The lzw1 packages are probably small enough that they should include the
-dev functionality in the runtime package.

	Thanks
