OK, the "unable to bind" error is unrelated to the "unable to copy
PPD file" error.

When you say "Listen localhost:631", CUPS tries to bind to both the
IPv4 loopback address (127.0.0.1) and the IPv6 loopback address
(::1).  If you don't have IPv6 enabled on your system, then it will
report that error.  You can avoid the error by specifying an IPv4
address, like "Listen 127.0.0.1:631".

The second error is probably a permissions or disk space issue; look
further down your error_log file for the CUPS-Add-Modify-Printer
request and see what is reported there...
