In my case, I compiled libRocket like this:
cmake
-DCMAKE_INSTALL_PREFIX=../panda3d-1.8.0/thirdparty/linux-libs-x64/rocket
-DBUILD_PYTHON_BINDINGS=onwith installed Boost. Another try, like you mentioned, I ignored the thirdparty dir and just installed it on my “buildbot”. Without any success :-/
Well, did it build _rocketcore.so at all? Does “find . -name _rocketcore.so” turn up anything? The CMake output should also shed more light on what’s going on.
Is it possible that you have multiple versions of Python installed, and that you built Rocket against a different version of Python that your version of Panda was built against?
Yes, I’m quite sure, there was the _rocketcore.so (which made my surprise perfect XD). In the meantime, I deleted the virtual machine. Was Xubuntu 12.04 with just “standard” pre-installed Python, no other versions. Maybe I’ll set up an new VM tomorrow and save the output for you.
OK, well, that indicates that it’s simply an installation failure. If the file existed, but Python could not load it, then it simply wasn’t in the right directory (or built for the wrong version of Python as I suggested earlier).
Well, yesterday I’ve set up a new virtual machine, this time Ubuntu 12.10 Quantal. You’re thoughts were right, 2 different versions of python (2.7.3 and 3.2). I compiled libRocket like this:
cmake -DBUILD_PYTHON_BINDINGS=on -DPYTHON_EXECUTABLE=/usr/bin/python2.7
make -j 5
sudo make installCompiling went through, and there was an _rocketcore.so in the Build-directory. Install output seems a bit strange:
buildbot@buildbot-virtual-machine:~/libRocket-master/Build$ sudo make install
[sudo] password for buildbot:

Build terminated.Bullet doesn’t even compile, but that’s unimportant for me.
EDIT #1: compiles with installation in the thirdparty-dir. Will post the result later 
btw, thanks for your patience, rdb
EDIT #2: compiles (still no Bullet, FFTW, artoolkit). Had to fix makepanda (which didn’t found libRocketCore.so.1,).
Line 5745:

But unfortunately, still no _rocketcore.so
If I copy my compiled _rocketcore.so to /usr/lib/python2.7/dist-packages, it is found but I get a segmentation fault.
OK, that makepanda issue is on my list. It doesn’t seem to detect libraries in /usr/lib/x86_64-linux-gnu for some reason.
The removed rpath entries are normal and expected.
As for _rocketcore.so, what’s the error you’re getting? You’re supposed to be able to import it from Python 2.7 without a problem. You say “no _rocketcore.so”, but clearly you’re acknowledging that it exists on your system, so I don’t know what you mean.
Uh, I’m sorry, didn’t express that clearly. libRocket is compiled, and there is an _rocketcore.so, located at ~/panda3d-1.8.0/thirdparty/linux-libs-x64/rocket/lib/python2.7/dist-packages/_rocketcore.so (the source dir) respectively /usr/local/lib/python2.7/dist-packages/_rocketcore.so (installed on the virtual machine). But in the built .deb-package, the file is missing and isn’t found.

There are many builds for major distros.
