I'm not on a mac, but it could be the shell mutating the comma or it could 
be the drawtext filter, don't know. You might try assembling the filter 
string into a shell variable and dropping that into the command line. Also, 
try echo-ing the command like into a file to see if the commas are correct.

You might also try the 'textfile' option instead of 'text' to avoid any 
munging the shell might do.
