*  lchmod  issue #467, peter1000

https://github.com/pydata/conda/issues/467

I clean installed miniconda27 and also miniconda33 (linux debian 64)

building appdirs seems to work now on both: cached also an other error I got when building an other package

PermissionError: # e.g. /etc/mtab

tested it only on: only on linux debian 64 wheezy
