just saw this.  This works unless you have two versions of gcc 
installed.  The c++11 abi emitted by gcc-4.7 and 4.8 are different and 
since you link against the latest version (see the ordering of 
directories in /etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf), 
building with the earlier gcc can cause breakage.  We may not want to 
support such a situation but I'd like to.
