I just typed into the terminal HVite -V. The result was that some HTK version information was being displayed.

Everything seems to be OK with my HTK installation.
I found this tip in this how-to:
“Type in “HVite -V” in a Command Console Window;
if your system lists all the options available to the hvite command, then HTK is installed properly.”
