absolutely.  i've an up-to-date osx 10.4.8 install, w/ latest XTools
etc from Apple.

ah. i'd thought it was *requried* for the extended-attributes support.
 my mistake.

hm. that should be in search path.  given that it doesn't work anyway, the c

no.  i did not install the rpms.  rather, per my original post (iirc),
i extracted the sources from the rpms (via cpio extract ...) in order
to get at the header files that the build was complaining about as
missing ...

givenn some of your comments, i think i'll need to replicated & post
my results ... what i'm hearing you say,  and what i remember
happening, are different.

which i'll do when i'm not so dog tired.

thanks, and i'll follow up soon.
