Ups. If I change my compile command to:
g++ ssg.cc -o ssg_test -lplibsg -lplibssg -lplibul -lGL
I get the following error instead:
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.2/../../../libplibssg.a(ssg.o)(.text+0x71e):
In function `ssgCullAndPick(ssgRoot*, float*, float*)':

float, float, float*)'
...

: undefined reference to `sgMakeNormal(float*, float const*, float const*,
float const*)'
collect2: ld returned 1 exit status
