What is your full configure line?

I didn't configure anything, I just copied the .so file into the apache modules directory and started check, how written in installation instruction of Active State Komodo.

Which configuration do you mean and how do I get the configure line?

PHP's configure line... you can see it by checking the output of the phpinfo() call.

Here is the php info line...

There must be something wrong with how this module was compiled, because when I do it myself it works just fine:

Perhaps you should contact the Active State people about this (and feel free to point them to this report of course).
