phpinfo() output with no configure command

[Danzzz]

Hello,

I have ubunut6.06 server runing. I installed a php5.1.2 with apt-get.
Now I should upgrade to php5.2 and there's no package.

So I have to compile by self. I want to use the same
./configure command like for the php5.1.2.

In php, there is a function "phpinfo()". With this function you
can display the used "configure command", but
there is no "configure command" in the ouput, you can
see a screenshot here:

After the row "Build Date" should be a row "Configure Command".

Does anyone know which "configure command" was used to build
this php5.1.2?

Best regards,

Daniel
