if you used the make/configure build you can see the configure line near
the top of config.status

is there any chance of compiler mixup, i.e. is the compiler used to
build OpenSG the one you've shown the specs for ?
AFAIK C++ standard compliance/support improved drastically with the gcc
3.4.x release series, so this might be a problem with the fairly old
compiler.
Have there been any warning when compiling
Source/Base/Field/OSGTypeInst.cpp or any other files that use
SField<Color3f> or SField<Vec3f> etc. ?
Can you try using objdump and grep to see if the symbols are present in
any of the .o files ?
Sorry, I find linker errors always very puzzeling and unfortunately
quite hard to debug,
Carsten
