It's in GNU textutils, so it will be on pretty much ever Linux system.
It's also on BSD, SunOS, and SCO.

Unfortunately, that doesn't work -- you need to give a range for the !
command.  "!wc <enter>" from command mode will select the current line
(because of the "w" command) and then try to filter it through "c".

Ooh, cool!  I didn't realize the difference between

:[range]w! wc

and

:[range]w !wc

That spaces makes a lot of difference.
