install-info question

[Orion Poplawski <orion cora nwra com>]

My recent release of plplot resulted in the following being output 
during the yum update:

install-info: menu item `The PLplot Plotting Library' already exists, 
for file `(none)'

The %post script is:

/sbin/install-info %{_infodir}/plplotdoc.info %{_infodir}/dir || :

Which is pretty much straight from 
http://fedoraproject.org/wiki/ScriptletSnippets?highlight=%28install-info%29

Here is the head of plplotdoc.info:

This is info/plplotdoc.info, produced by makeinfo version 4.8 from
plplotdoc.texi.

START-INFO-DIR-ENTRY
* The PLplot Plotting Library: .   ???
END-INFO-DIR-ENTRY



So, what's wrong here?

Thanks!
