voxmesher error

When I run the commad of "voxmesher Berea.conf", it shows voxmesher:can not find the command. This is because that I do not install the tarantula on my system. I search on the Internet, but I find little about the voxmesher.

I want to know how to install the tarantula and use the command of voxmesher.

Many thanks for your help.
