tmpdir error while installing 5.7.5 binaries on sandbox

[lalit]

Getting unknown variable 'tmpdir=/root/sandboxes/msb_5_7_5/tmp' while installing 5.7.5 binaries on sandbox.

Details:
Sandbox version: 3.0.45
mysql version: 5.7.5-m15
OS: ubuntu 14.04

CMD #make_multiple_sandbox --how_many_nodes=5 --group_directory=multi_msb_lab_5.7 /opt/mysql-5.7.5-labs-preview-linux-el6-x86_64.tar.gz

NOTE:1. same 5.7.5 binary installation working fine for normal installation. i.e without sandbox
            2. tried 5.6.* binary installation on sandbox working fine for all kind of setups.

As per mysql DOC.
"If you have set a custom TMPDIR environment variable when performing the installation, and the specified directory is not accessible, mysql_install_db may fail. If so, unset TMPDIR or set TMPDIR to point to the system temporary directory (usually /tmp)."

I checked on my ubuntu 14.04 , there is no custom TMPDIR environment variable set.

Please use the latest release of MySQL Sandbox, where this issue is already resolved.
