Searching bullet source files in wrong folder

[CommanderCero]

Hello,

when executing the following Code-Snippet with gdb:

from roboschool.scene_abstract import SingleRobotEmptyScene
scene = SingleRobotEmptyScene(gravity=9.8, timestep=0.0165, frame_skip=1)
scene.episode_restart()
scene.cpp_world.load_mjcf('/home/username/anaconda3/lib/python3.7/site-packages/roboschool/mujoco_assets/inverted_pendulum.xml')

I get the following Error-Message:
Program received signal SIGILL, Illegal instruction.
btMatrix3x3::setRotation (this=0x7fffffffb410, q=...)
at /root/.forked_bullet/include/bullet/LinearMath/btMatrix3x3.h:211
211 /root/.forked_bullet/include/bullet/LinearMath/btMatrix3x3.h: No such file or directory.

So for some reason it tries to find the bullet files in the folder of the /root/ user.
But I never had the forked_bullet in the /root/ folder its under /home/username/.
