Basically, I've discovered two problems:

1) Some packages are not 64-bit clean, so they need to be compiled and 
run as 32-bit executables

2) I've tried compat_netbsd32 on sparc64, but parts of it seem to be 
broken, see the following PR: 
http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=28930
What this means is you can't run 32-bit gcc to build 32-bit packages 
from pkgsrc on sparc64, and native 64-bit gcc does not support -m32 
option :-/
