phpsysinfo eval : 2 Message : parse_ini_file(/usr/share/phpsysinfo/data/distros.ini): failed to open stream: No such file or directory File

There is a simple fix for this in version 3.0.5:

Copying the data directory from the source .tar.gz (available from http://phpsysinfo.sourceforge.net/) to /usr/share/phpsysinfo and that fixes the error (so you get a new /usr/share/phpsysinfo/data directory).

Simple.
