I just noticed that two packages (acroread? and xpdf?) in the graphics
category have corrupted listings on
ftp://ftp.netbsd.org/pub/NetBSD/packages/pkgsrc/graphics/README.html:

They appear as

 :                        Display tool for PDF files, including encrypted ones. 
 :                        Display tool for PDF files. 

at the top of the list.

Cheers,
Brook
