Sorry to answer so late.

ptlib/opal libraries evolve continuously without retaining backward 
compatibility.  So it is generally impossible to use an old ekiga with 
new ptlib/opal.  If you really wish to do it, look at 
http://git.gnome.org/browse/ekiga/log/ and search for changes fixing 
your compilation errors.  For ex., for your errors look at:
http://git.gnome.org/browse/ekiga/commit/?id=72d7b95bd8df3b667
http://git.gnome.org/browse/ekiga/commit/?id=6eb6995892c49226
etc.

I would really advise to use 3.3.0 (or the very soon 3.3.1).  If you 
have problems with gtk or other lib dependency (which one?), I think it 
is better to use ekiga 3.3.0/1 and revert changes which push the 
dependencies.

Finally, I am not sure that updating ptlib/opal will allow you to use 
H323, I suppose that ekiga too needs a modification.  Whether this 
modification consists in only ekiga.schemes change (adding H323 to the 
codecs concerned) or other changes, I could not answer yet...
