I also received these same php errors. If I recall correctly the issue was related to wrong PHP path in the /usr/sbin/ scripts. Atleast for Ubuntu and Centos #!/opt/bin/php
does not work (should be /usr/bin/php).
Also access rights gave me some problems.
I managed to get Thermiq interface running on ubuntu, but since Ubuntu 11.10 is rubbish (needed a reboot almost every day…). I have now changed to Centos 6.2 and I have not had the time to set up Thermiq. taloLogger is gathering information for now.
