removing psa 8.3 (and avoiding it's influences)

[CosmicD]

HEllo,

I wanted to install psa 8.3 on my debian etch system to see what has improved,

but at the installation it just dies and leaves my system incomplete, I had php5 enabled for apache and now it uses php4 which i don't want. I wanted to remove everything that the psa installer installed but, how do you start with that ?

can i possibly revert to my old settings?
