Try to shorten config_directory path

mvdbeek · mvdbeek · commit efc5f30a92b1 · 2016-04-24T12:46:29.000+02:00
Conda has limitations in the length of the placehodler path. This can be easilly used up on OSX, since OSX provides a long tmpdir path. If that is the case, we can try to use mkdtemp with the /tmp directory. May be a workaroudn for #433
