Hi All,

I just did a clean install of Xubuntu 20.04.  I also installed emacs27
(from this repository:ppa:kelleyk/emacs)

When I try to export any snippet from org-mode by calling
org-export-dispatch, my freshly installed emacs complains:

"let: Symbol’s value as variable is void: org-table-header-line-p"

Any help would be much appreciated
