XBT source got error.

Can't install xbtt from source: http://xbt.googlecode.com/svn/trunk/xbt/Tracker because file /Tracker/server.cpp on line 189: " for (auto& j : i->second.peers) " will cause this error:

[root@vps Tracker]# ./make.sh

So PLEASE CHANGE line 189 to: " BOOST_FOREACH(auto& j, i->second.peers) "

I had the same problem with compiling tracker on latest CentOS (6.5) couple days ago.
This type of range syntax in operator "for" can't be compiled by my version of gcc.
Line 189 in server.cpp was changed in revision 2397. So I've downloaded revision 2396 for compilation.
Updating gcc to 4.7 in CentOS is planned in version 7, as I understand.
