I've seen issues with building ptlib/opal in the past if you don't
have all the right dependencies in place. The ptlib/opal/ekiga combo
for ekiga 4.0 build just fine with gcc 4.7.x as that what Fedora 17/18
use.

The dependencies (Fedora naming so will need adjusting for other
distros) I have for ptlib are:

BuildRequires:	pkgconfig, expat-devel, flex, bison
BuildRequires:  alsa-lib-devel, libv4l-devel
BuildRequires:  openldap-devel, SDL-devel, openssl-devel
BuildRequires:  boost-devel, pulseaudio-libs-devel

The configure I use is:
%configure --prefix=%{_prefix} --disable-static --enable-plugins
--disable-oss --enable-v4l2 --disable-avc --disable-v4l --enable-pulse

I disable the old v4l and just use v4l2 as it's been dropped from newer kernels.

Deps for opal are:
BuildRequires:	ptlib-devel = 2.10.9
BuildRequires:	openldap-devel
BuildRequires:	openssl-devel
BuildRequires:	libtheora-devel
BuildRequires:	speex-devel
BuildRequires:	SDL-devel
BuildRequires:	expat-devel

and the configure line I use is:
%configure --disable-silk
