I'll put some unrelated comments in here, hope you don't mind ;)

These vectors do not hold nodes, but geometries (which are derived
ultimately from NodeCore) so the name could be a little misleading.

This test will always fail, a core is never derived from Node or NodePtr
- I believe you meant .isDerivedFrom(OSG::Transform::getClassType()) ?

not required, node is a NodePtr.

Now to what you actually asked for ;)

try the following call instead. Your enter method is not a free
function, hence you need to supply an object to which it can be bound
when called (I hope I picked the right functor creation function).
traverse(tempLeg, osgTypedMethodFunctor1ObjPtrCPtrRef<Action::ResultE,
Leg, NodePtr>(this, &Leg::enter));
The functor creation functions are in
Source/Base/Functor/OSGTypedFunctors.h and this page
http://www.opensg.org/doc-1.6.0/Traversal.html of the tutorial has a
similar example with a class counter (in the lower third of the page).
If it's not working please ask again.
Hope this helps,
Carsten
