Nice. Some comments: - It doesn't check if you already have php 5.4 installed - It doesn't believe you may not want to install it:
Install PHP in ~/.mediawiki/php [y/N]: N Downloading PHP 5.4- using wget --2012-07-27 03:06:23-- http://snaps.php.net/php5.4-latest.tar.gz
(...)
- The 'latest' download url for php I was using now only gives out old
RC versions instead of the latest php5.4. Not sure how to fix that easily. (I wonder if I should fix these issues by switching the tool to python)
It's getting a php 5.5 snapshot. Perhaps not so bad.
