[OS X TeX] Loss of Greek Porson font functionality

[David Derbes]

About a year ago, I downloaded from Antonis Tsolomitis's web site a  
gorgeous Greek font called Porson. I installed it following his  
included instructions, and it worked fine.

It stopped working yesterday. I reinstalled it, but still no go. I  
have no idea what is going wrong. I attach the output of the console  
that seems to be telling me something, but I have not been able to  
respond appropriately to the messages:

(the rest is like this; the characters in the Greek all being mapped  
to .notdef.)

I am running OS X 10.10. My guess is that the change from 10.9 to  
10.10 clobbered it, but I really do not know.

When I reinstalled, I put all the files into the tree \local\share 
\texmf.tetex, ran (following Bruno Voisin's excellent guide) the  
commands

sudo texhash
sudo udpmap --enable Map gfsporson.map
sudo mktexlsr
sudo udpmap-sys

but there is no indication that Porson was added to anything.

Any help would be most welcome.
