You are correct, cylinder vs cylinder and cylinder vs capsule
collisions do not currently work. We are still waiting for someone to
submit patches to support these collision combinations.

For a complete list or what's supported, check out this handy matrix
in the wiki manual:
as you can see, that's pretty much the only hole in ODE's collision
support right now. (convex hull support is still early in development)

If you are using the default config.h file and projects included with
a release since 0.6 then it's very likely that you are. The definitive
test is whether trimesh collisions work in the tests. If "#define
dTRIMESH_ENABLED 1" is in config.h then it should work.
