There are several physics engines available for use in OpenSim. Currently, they are "basicphysics", "OpenDynamicsEngine", "RealPhysX" & "bulletx". The plugin 'basicphysics' is the default and can be seen in the OpenSim.ini file.
When starting OpenSim in either Windows or Linux, one can add "-physics=OpenDynamicsEngine" to run the OpenDynamicsEngine instead of basicphysics, or change the corresponding parameter in OpenSim.ini.
When starting OpenSim in Windows, one can add "-physics-RealPhysX" if one has the appropriate DLL's which are not shipped with OpenSim due to EULA constraints.
To conclude. basicphysics & OpenDynamicsEngine both are appropriate for Linux and in addition, RealPhysX is appropriate as an option for Windows if the supporting DLL's are available.
Compiling libode from source (Linux)
Get the latest source code Vers. 0.8 from http://www.ode.org Unpack it, switch to the libode source directory and compile it as follows:
./configure --with-trimesh=gimpact --enable-shared ./ make -k
Copy now the libode.a and libode.so files in the ode/src subdirectory to the opensim bin directory (after having backed up the original files there).
You can additionally try to configure libode with: --enable-double-precision and --with trimesh=opcode
