[Ekiga-list] What libraries and where headers to make ptib

[gegetel <geo cherchetout laposte net>]

Hello,

I am an old beginner using Mandriva 2008.1 and i should like to try svn 
Ekiga. My guide is this page: 
http://wiki.ekiga.org/index.php/Additional_Information

To configure and make ptlib, what libraries are strictly needed for Ekiga ?
(I have already flex, bison , libldap2.4_2 and libldap2.4_2-devel.)

Where can i find the other libraries and/or headers that are needed ?

Thank you for your help.
