emacslient is a command line utility and is usually installed along
with Emacs.  You need to start the server inside Emacs with M-x
start-server.  Then you can do something like:
   shell$ emacsclient -eval '(emacs-version)'
   "GNU Emacs 24.0.50.2 (i686-pc-linux-gnu, GTK+ Version 2.12.12)\n of 2010-09-27 on ix"
   shell$

You seem to confuse something here. swank::eval-in-emacs is a CL
function and you need to call it in the CL process.

cl-user> (swank::eval-in-emacs '(emacs-version))
"GNU Emacs 24.0.50.2 (i686-pc-linux-gnu, GTK+ Version 2.12.12)
 of 2010-09-27 on ix"

works independent of the the current frame/buffer.
