PHP imagecreate() not found but compiled with GD

Here is what I get:

[code:1:be41bc7717]
<b>Fatal error</b>: Call to undefined function: imagejpeg() in <b>image.php</b> on line <b>56</b><br />
[/code:1:be41bc7717]

I am positive it is compiled with GD so I don't get the error

I need to install the linux-jpeg package

then

I need to recompile PHP with:
