So it seems. Also throwing that strange "cannot allocate zu bytes" into 
google says you're not the only one seeing it, see the "Problems on AIX" 
threads starting at http://mx.gw.com/pipermail/file/2012/000965.html

Hmm, when it should only warn, not error out on non-executable files. Of 
course it'll still fail to get the dependencies right, so the best 
option is to fix (by updating I suppose) libmagic.
