This part is not needed. :package-version is used to specify when
a defcustom was introduced or when its default value last changed.

inferior-STAT-program-name is a variable defined in "ess-custom.el".
The error probably comes from the fact "ob-stata.el" is loaded before
"ess-custom.el" is.

You may want to tell the author of "ob-stata.el" about it. It is missing
a (require 'ess) somewhere in the library.
