This shouldn't happen.

A SuSE mailing list post recommends installing the php4-session package 
(probably instead of some other package - session support is compiled 
right in, not added as a module).

PmWiki should run just fine with either PHP4 or PHP5. I had issues with 
the mailprotect module on 4.1.something, but the core ran just fine.

That should work. However, I wouldn't recommend that: any future 
upgrades may overwrite files that you have edited.

However, you could copy something like Test.Test to pmwiki.d, edit it so 
it gets copied to wiki.d, check what ownership and permission were 
applied by Apache, and change all files in wiki.d to match. (Don't 
forget to clean up and remove Test.Test in both directories afterwards *g*.)

I did "SuSE session_id" :-)
