Thanks for the quick reply. I've tried this and attached the (heavily snipped) 
output. The main thing I noticed is that it is scanning paths 
like 
/home/joe/programming/lilypond/Documentation/user/out-www/source/user/out-www/source/user/out-www/lily-3c5cc96107.pdf.
 
Since "source" is a symbolic link to "../..", could it be getting trapped in 
a loop? Anyway, I don't really know how to interperet the output, so I'll 
attach it. If you want to see a less abbreviated version, I can do that too.

In case it makes a difference, I am using tetex on gentoo.

I tried "emerge -e world" to reinstall/upgrade every program on my computer 
but it didn't change anything. My current version of tetex is 
tetex-3.0_p1-r3, which is the latest version available on this distribution.

Thanks,
