Installing Bullet Engine - Ubuntu

Installing Bullet Engine - Ubuntu

I'm writing program in OpenGL and i wanted to use Bullet Engine.
Unfortunately after the installation (i think all done correctly), when i
try to compile my program it shows:
g++ -c main_file.cpp -o main_file.o
In file included from
/usr/local/include/bullet/btBulletCollisionCommon.h:22:0,
from /usr/local/include/bullet/btBulletDynamicsCommon.h:20,
from main_file.cpp:2:
/usr/local/include/bullet/BulletCollision/CollisionDispatch/btCollisionWorld.h:73:34:
fatal error: LinearMath/btVector3.h: No such file or directory
compilation terminated.
make: *** [main_file.o] Error 1
I tried with this tutorial :
http://www.warp1337.com/content/compileinstall-bullet-physics-engine-276-svn-ubuntu-910-howto
And few others which was similar to this one. And nothing worked. Always
same problem.
