Now the bad news.

The new eglibc 2.16 defines TIME_UTC macro which is part of C11 and
clashes with boost::TIME_UTC which means boost1.49 does not compile
any more.
(anything using boost/thread/xtime.hpp template or explicitly using
boost::TIME_UTC)
Luckily this is fixed in boost1.50 by means of renaming the macro to
boost::TIME_UTC_
There are rdeps which actually use boost::TIME_UTC macro all of them
need to transition to boost1.50 and boost::TIME_UTC_
