*** missing separator (did you mean TAB instead of 8 spaces?). Stop.

Fix
===
Substitute 8 space with tab via "vim" editor using following command
:%s/^ \{8}/^I/

If it not replacing 8 space with tab, then edit :%s/^ \{8}/^I/ and remove "^I" and press "Tab", so we can see "^I" again there. Then run it again.
