[Ekiga-list] Compatibility question

[geo cherchetout <geo cherchetout laposte net>]

Hello,

To day, following links given in this page at the "stable" line:
http://wiki.ekiga.org/index.php/Download_Ekiga_sources
I installed from tarballs ptlib-2.6.7, opal-3.6.8 and ekiga-3.2.7.

Then I try to launch ekiga :

$ LD_LIBRARY_PATH=/usr/local/lib /usr/local/bin/ekiga
/usr/local/bin/ekiga: error while loading shared libraries:
libopal.so.3.6-beta9: cannot open shared object file: No such file or directory

Ekiga-3.2.7 asks for libopal.so.3.6-beta9 but the library provided by
opal-3.2.7 is libopal.so.3.6.8.

In the same way, Ekiga-3.2.7 asks for libpt.so.2.6-beta8 but the library
provided by ptlib-2.6.7 is libpt.so.2.6.7.

Is this an error to suppose that these 3 recommended "stable tarballs" would
be compatible with each other ?
