v2.19.82 documentation unusable?

[Patrick Karl]

I have lately been trying to move from v2.19.81 to 2.19.82.  The biggest 
problem I see at this early stage is that
 v2.19.82 documentation is apparently dependent upon a new font, Emmentaler-20. 
 Or at least I 
get an error message such as:

Cannot find or create the font Emmentaler-20. Some characters may not display 
or print correctly.

or 

Cannot find or create the font TeXGyroSchola-Regular. Some characters may not 
display or print correctly.

I have downloaded the pdf version of the documentation.  I’m running OS X 
10.11.6 on a mac pro and a macbook pro.

Does anyone have any helpful information here?  Does any of the documentation 
address this problem, which I have not encountered in the past (I’ve been 
running LilyPond since 2.14).
