 7Ok.. the code to find the filename for __getattr__ should look
 8something like:
 9
10import os
11from macholib.dyld import dyld_find
12
13def find_lib(name):
14     possible = ['lib'+name+'.dylib', name+'.dylib',
15     name+'.framework/'+name]
16     for dylib in possible:
17         try:
18             return os.path.realpath(dyld_find(dylib))
19         except ValueError:
20             pass
21     raise ValueError, "%s not found" % (name,)
22
23It'll have output like this:
24
25 >>> find_lib('pthread')
26'/usr/lib/libSystem.B.dylib'
27 >>> find_lib('z')
28'/usr/lib/libz.1.dylib'
29 >>> find_lib('IOKit')
30'/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit'
