Whoops. This one breaks when check_create_long_filename() succeeds. I've 
updated the git repo with the following hunk instead of above:

+        # If we don't have permissions to SSTATE_DIR, suggest the user 
set it as an SSTATE_MIRRORS
+        try:
+            err = testmsg.split(': ')[1].strip()
+            if err == "Permission denied.":
+                testmsg = testmsg + "You could try using %s in 
SSTATE_MIRRORS rather than as an SSTATE_CACHE.\n" % (sstate_dir)
+        except IndexError:
+            pass

Tested with both an SSTATE_DIR I can write to and one I can't.

Thanks,
