Qt4-libs [from pkgsrc] build failure on -current ?

I have NetBSD/sgimips , more-or-less -current

NetBSD sgio2 5.99.20 NetBSD 5.99.20 (GENERIC32_IP3x) #2: Sun Oct 11 16:02:45 GMT 2009  guest@slax:/mnt/hdb2/obj/sys/arch/sgimips/compile/GENERIC32_IP3x sgimips

After downloading and unpacking pkgsrc  snapshot from 16 10 2009 I tried to build kde3, but it fails (not strictly, but there was warnings about known vulnerabilities, so I skipped it). Then I tried to build kde4, and  compilation stopped here:

----

this is with gcc
gcc (GCC) 4.1.3 20080704 prerelease (NetBSD nb2 20081120)

and binutils 
as --version
GNU assembler 2.16.1

Anyone know any workaround? (this machine, 180mhz r5k CPU/256MB RAM SGI O2 a bit too slow for building just everything)
