Please make sure you are checking out from cvs HEAD. What do the following commands return?
cvs status -v acs-tcl/tcl/parameter-procs.tcl
grep localize acs-tcl/tcl/parameter-procs.tcl
You should have the localize switch in the procedure defifinition for parameter::get in that file.
If you want I18N and the latest stage of development, make sure to never use any -r switch in the cvs commands in the installation instructions.
