Problems with `flair`

[luk-brue]

When I tried to install DoSStoolkit, I could not successfully install it, because the dependency flair was removed from CRAN last summer. So I installed flair from github and retried installing DoSStoolkit, and it worked.
But now I am running into new issues when trying to run a tutorial.
Here is the error produced:

Quitting from lines 229-234 (totally_addicted_to_base.Rmd) 
Error in knit_print.with_flair(.) : 
  could not find function "knit_print.with_flair"
Calls: sourceWithProgress ... withVisible -> eval_with_user_handlers -> eval -> eval -> %>%
Execution halted

Is there a way I can install the old version of flair to make your awesome tutorial package work?
