I could fix it by the same hack as #124 (comment)

my environment is Ubuntu 14.04.1 server

$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.1 LTS"
$ uname -a
Linux kinoko 3.13.0-62-generic #102-Ubuntu SMP Tue Aug 11 14:29:36 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

and, I use the most recent cf_nise_installer.

    Bump cf-release to v215

Hi, thanks for the feed back.

Unfortunately, I cannot reproduce the issue you are experiencing.
I tried this example and succeeded to start the php-info app.

Please make sure you updated the submodule of cf-release in your repository directory when you deployed your devbox.
