graphics/xsane build failure

[maximum entropy <entropy%entropy.homeip.net@localhost>]

I'm having trouble building graphics/xsane on this system:

NetBSD zippy.local 5.0 NetBSD 5.0 (GENERIC) #0: Sun Apr 26 18:50:08 UTC 
2009 
builds%b6.netbsd.org@localhost:/home/builds/ab/netbsd-5-0-RELEASE/i386/200904260229Z-obj/home/builds/ab/netbsd-5-0-RELEASE/src/sys/arch/i386/compile/GENERIC 
i386

I have been getting this error for about 2 weeks now, maybe more.  The 
rest of pkgsrc has been fully updated each time, and have also cleaned 
out the work directory before trying to build.  Any help would be 
appreciated.

Script started, output file is typescript
