Perhaps somebody else can help to identify where the problem's
occurring... see truss output down a bit further,,,
Maybe I've got a dud library... one of
/usr/lib/liblpr.so
/usr/lib/libsocket.so
/usr/lib/libc.so
/usr/lib/libnsl.so
/usr/lib/libdl.so
/usr/lib/libmp.so
or even
/usr/lib/locale/en_AU/en_AU.so
