You might want to try the 1.2-Beta binary release somewhere on
ftp.netbsd.org. 1.1 has a bug in the dynamic linker module that does
not flush the icache after making changes to the text segment. This
causes all sorts of problems on machines without cache-coherent
instruction caches (i.e. SS5).
Alternatively, if it works, you can try to rebuild and reinstall ld.so
from the 1.2-Beta source.
Note also that SS5's aren't tested yet, so there could be other problems
lurking which I haven't seen...but this one sounds like the linker bug.
