I think this is the most simple and most clear. If you go by awk and maybe print out the variable names as text together with the = and the value, you'll have to eval the output so it will be recognized as shell variables.
I would stick with the crude solution. There is no other solution coming to my mind that would be shorter. Maybe another reader has an idea.

NAME

       CPANPLUS::Shell

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
