Comment (by sergey+macports@…):

 I haven't experiences this problem until OS X 10.10 Yosemite and Emacs
 24.4. The original workaround recipe didn't work and I wasn't kin on
 modifying Tramp source. The following worked for me right before starting
 Tramp: `M-x setenv TMPDIR /tmp`. I only use it btw to sync up Org mode
 files using MobileOrg.
