up2date anomaly - "hdr" vs "rpm"

[Price Technology]

Just finished with a fresh install of FC2 on my laptop, followed by  
running up2date and manually installing the kernel-doc package.  My  
up2date icon is now a very happy blue ball.

The anomaly I'm seeing is when I look in the up2date folder, I see many  
header files without corresponding rpm's.  This same behaviour was noted  
on my desktop when I installed / updated it.

Both machines were "Everything" installs, and up2date runs in it's default  
configuration except that I chose to keep the files after installation.

Since it happened on both machines, maybe it's normal.  When I was running  
Shrike however I had "matched pairs" of header and rpm files.  I remember  
this because I was using dialup at the time and up2date kept timing out so  
I would run it, grab the headers, then cancel and visit my favorite mirror  
to download the rpm's via ftp.  Once I copied the downloaded rpm's to the  
up2date directory, up2date happily gobbled them right up.

Anybody else seen this behaviour in up2date ?? Better yet, anybody got an  
explaination ??

Thanks
