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