[kronolith] Fatal error: Call to undefined function: iswarning()

Full error:

Fatal error: Call to undefined function: iswarning() 
in /usr/local/httpd/great2cu/horde/kronolith/lib/Driver/sql.php on line 64

using:
horde 2.2.1
kronolith 1.0
Suse Linux 8.0

I tried postgres and mysql, both work fine with other horde features like sork.

I suspect I need a new version of php, I am currently running 4.1.0.

Is my assumption correct, or might it be a config error (sure hope so)

Thanks in anticipation,

Lody Hoekstra
