pkg_info -qLx "^${PKG}-[0-9,\._]+\$"
                -- 1--           -2-

@1: shell evaluates before regex. Use braces so that end of variable is 
explicit
@2: this shouldn't be evaluated by the shell, so escape it with a backslash. 
It's passed as dollar sign to the command.

Also, I'm relatively sure it needs -X for the + sign, but haven't tested.
