I think the problem with orocos.rb is related to some
linking problems of the orocos extenstion.<br>
I attached the ldd output and the CMakeCache from my
installation. So Far i see it should work.<br>
I compared the CMakeCache with my local one and can't find
the fault here.<br>
<br>
Has someone i idea what's going on here?<br>

<div>The ruby extension is not linked against ruby. In general
it is not nice but should not be a problem because the symbols
are already known if the extension is loaded by ruby. </div>

<div>You can try the following and post the output for all
steps:</div>
