The correct name is auto_path.  The docs say so:

       auto_path
              If set, then it must contain a valid Tcl list giving directories
              to search during auto-load operations (including for package in‐
              dex files when using the default package unknown handler).  This
              variable is initialized during startup to contain, in order: the
              directories  listed  in the TCLLIBPATH environment variable, the
              directory named by the tcl_library global variable,  the  parent
              directory of tcl_library, the directories listed in the tcl_pkg‐
              Path variable.  Additional locations to look for files and pack‐
              age indices should normally be added to this variable using lap‐
              pend.

              Additional variables relating to package management exist.  More
              details  are listed in the VARIABLES section of the library man‐
              ual page.

Where did you see "autopath"?

call: man n package
 
→ check for the term "path" → not found in manpage
→ a lot of text but NOT a single word how to setup the path to get the package found !!

after some research the right name is "auto_path"
