You're good then. The releases from http://ardour.org/download are done
The installer does check and prints a warning and asks for confirmation
if the gcc-abi of the ardour binary does not match the system.

The usual result on a gcc-abi mismatch is that the plugin(s) won't load
(but in some rare cases it may also cause crashes: eg. eq10q).
In most cases (guitarix, ingen, amsynth,..) this also only affects the
plugin GUI (not the plugin itself).
If it really renders a session unloadable you can run
and remove the plugins (or simply get a different version).
The Note on http://nightly.ardour.org/ has a list of currently known
plugins that use C++11 or depend on libs which use C++11 (mainly
libglibmm provided by the system vs libglibmm that comes with Ardour).
Known affected plugins: abgate, ams-lv2, amsynth, beatslash,
deteriorate, eq10q, guitarix, ingen, midimsg, newtonator, triceratops,
