oclHashcat not working

I'm new to linux. I downloaded the latest oclHashcat version with the terminal ( apt-get install oclhashcat). When I open it, it said this:
./oclHashcat.bin: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory
I reinstalled it (apt-get install --reinstal oclhashcat) and got the same.
Please help. Thanks!
