Online installer fails when wget version is too old

[cawallin]

When the wget version is equal to wget-1.12-2.fc13 (and perhaps other versions), the online installer fails with the following message:
[root@cwallin-vagrant-master opt]# ./prestoadmin/install-prestoadmin.sh
--2015-07-20 14:05:04-- https://pypi.python.org/packages/source/v/virtualenv/virtualenv-12.0.7.tar.gz

This is a known issue:

We don't want to add --no-check-certificate to the wget in the online installer every time, though that does fix the issue. This error is found on CentOS 6.5.
