I use automatic build from network-manager team ppa 
you can see full build here
http://launchpadlibrarian.net/39701160/buildlog_ubuntu-karmic-amd64.network-manager_0.8-0ubuntu4~nmt4~karmic_FULLYBUILT.txt.gz

I think these are informations that you need
cd . && CFLAGS="-g -O2 -g -Wall -O2" CXXFLAGS="-g -O2 -g -Wall -O2"
CPPFLAGS=""
LDFLAGS="-Wl,-Bsymbolic-functions" /build/buildd/network-manager-0.8/./configure --build=x86_64-linux-gnu --prefix=/usr --includedir="\${prefix}/include" --mandir="\${prefix}/share/man" --infodir="\${prefix}/share/info" --sysconfdir=/etc --localstatedir=/var --libexecdir="\${prefix}/lib/network-manager" --disable-maintainer-mode --disable-dependency-tracking --srcdir=.   --with-dbus-sys=/etc/dbus-1/system.d --with-distro=debian --with-resolvconf=/sbin/resolvconf --libexecdir=/usr/lib/NetworkManager --with-pppd-plugindir=/usr/local/lib/pppd/2.4.4/ --with-crypto=nss --with-iptables=/sbin/iptables
