[lug] rpm build error: file listed twice

[D. Stimits]

I am trying to create rpm packages from a tarball that has the spec file 
in it, on a RH 7.3 machine. The rpm format for this version is not 
publicly available, the spec file is a remnant of the prior version of 
this software (which is publicly available in rpm format). The only 
apparent change for the spec file is the version number. The prior 
version can be turned into rpm format via the rpm -ta package.tar.gz, 
while this one fails, claiming a duplicate file:

RPM build errors:
     File listed twice: /usr/sbin/upsd

...in no way can I find where this is listed twice. I saw a couple of 
old google search items on this for other packages, but no answer. Has 
anyone here seen this error before, or have an idea of how to figure out 
why it thinks (falsely?) that the file is listed twice? This rpm does 
have subprojects, one for an UPS client, one for an UPS daemon, and the 
last for a cgi web monitor of the UPS server. Perhaps subprojects have 
something in common that it mistakes for being listed twice in a single 
project (but I have done a case insensitive rgrep with the path listed, 
and cannot find out how it is listed twice; an rgrep for the duplicate 
file itself, did not seem to reveal duplications that I could see).
