The DESCRIPTION file is a plain text file, not R code.  You don't need 
to source() it, you just edit it in a plain text editor (e.g. Windows 
notepad).  Many editors can read and write a variety of encodings. 
Notepad can handle ANSI (their name for the local encoding, usually 
something like latin1 in western languages) and UTF-8.  I'd recommend 
using ANSI, because notepad will probably write a "byte-order mark" that 
will confuse some other systems.

So if you can view all the files in notepad and they look okay, then 
save them using ANSI, and add the line

Encoding: latin1

to the DESCRIPTION file, and MacOS should be able to handle the package. 
  If you have a better editor I'd choose UTF-8 with no byte-order mark.
