I don't know what's wrong with the interfaces that you generated.

You can (as of yesterdays's server upgrade) get a copy of the
darwin-x86-headers64 hierarchy (including .cdb files) from:

'http://clozure.com/cgi-bin/viewvc.cgi/trunk/darwin-x86-headers64.tar.gz?root=svn&view=tar'

(via curl/wget/something like that) or via a browser by clicking on the
"Download GNU tarball" link at:

<http://clozure.com/cgi-bin/viewvc.cgi/trunk/darwin-x86-headers64/?root=svn>

Sort of looks like an error occurred after the libraries were mapped
into memory but before the new ObjC classes/methods could be integrated
into CLOS.  (Perhaps an error involving the foreign type
:<CAC>ONSTRAINT<A>TTRIBUTE, which is just typedef'ed to "int".  Yep,
that would be my guess.)

I don't know why that type can't be resolved; some things that'd
sometimes make that hard (chains of forward references to other types)
don't seem to apply here, so something more mundane (pathname issues)
might be involved.
