I think so. My speculation: If the newest Org is not yet in load-path when you load org-real, org-real's (require 'org) will pull-in built-in version of org-compat. Later, when load-path points to the newest version of Org, you load org-persist (org-persist does not exist in built-in version of Org), which relies on org-file-name-concat to be defined in the newest version of org-compat. However, built-in version of org-compat is already loaded by emacs and (require 'org-compat) inside org-persist does not trigger loading. Hence, you are getting > Debugger entered--Lisp error: (void-function org-file-name-concat) Best, Ihor
