The list of required PHP modules was supplied by Dmitry in respons to 
"FYI24 #6208: zlib must be compiled in to make an extension lookup" on 
July 7th, 2010 16:43h.

I simply picked one of the function supplied by these modules and check 
if this function exists.

Maybe we should first come to an agreement which modules are absolutely 
necessary:

- filter
- gd
- json
- mysql
- pcre
- session
- spl (seems to be needed by extbase)
- xml parser
- zlib
