That is a failure inside libmagic, rpm is only the messenger here.
It should be reproducable outside rpm with:

$ file -z -e tokens <path-to-buildroot>/foo/bar/

...assuming 'file' is linked against the same libmagic version as rpm, 
that is.

Also what 'ls -l' says about the file might help shed some light on it. 
Like Jay noted there's a 4G limit on individual files, but rpm should 
clearly report that with a "File <path> too large for payload" message 
so I suspect this is something different.

You should be able to get past it by doing 'chmod a-x 
%{buildroot}/foo/bar/' at end of %install section (and/or 
possibly adjust %files section to make it non-executable there too). The 
dependencies wont get recorded that way, but that can be worked around 
by manually adding them in the spec if need be.
