[R] rgl installation problems

[Prof Brian Ripley]

Here's what should happen on RH9 (with the latest libpng and gcc in 
/usr/local/lib)

g++ -shared -L/usr/local/lib -o rgl.so x11lib.o x11gui.o types.o math.o 
fps.o pixmap.o gui.o api.o device.o devicemanager.o rglview.o scene.o 
glgui.o -L/usr/X11R6/lib -L/usr/local/lib -Wl,-rpath,/usr/local/lib 
-lpng12 -lz -lm -lstdc++ -lX11 -lXext -lGL -lGLU -lpng12 -lz -lm

Note that he had no --shared but did have crt1.o, that is was trying to 
build a standalone executable and not a shared object.

Something is wrong with the R installation's rules to make shared 
libraries.
