[Linphone-developers] configue error

[Sheila Mae Secret]

Hi,
  I'm installing Linphone 3.3.0, stable version on Fedora 9 from the source code. I've installed all the dependencies like SDL, FFMPEG, SPEEX.
 All the installations have been successfull. But, when I try to
 configure the linphone installation, it gives me the following error.

********************************************************************

Please help me with this problem. Thanks!
