[ros-users] No module named PyKDL???

i'm a little confused about KDL and python. i have a C++ node that is using KDL just fine, so i know it's installed. however, i can't seem to get it imported into a python node. i should mention that i'm running boxturtle (installed just prior to the ROS tutorial at ICRA 2010).

in my manifest.xml, i have:

    <depend package="kdl"/>

(i've tried PyKDL, KDL, etc., but they cause errors during rosmake)

in my python code, i have:

    import PyKDL

following one of the KDL tutorial wiki pages.

when i try to rosrun the node, i get "ImportError: No module named PyKDL" (and kdl, KDL, pykdl, etc. don't work either)

is there something wrong with my installation? do i need to install python bindings to KDL separately?

thanks,

wes
