‘pow’ is not a member of ‘std’

[Maxim Smirnov]

While makeing (a freshly git pulled)MOSES, I've run into an error:

[ 68%] Building CXX object moses/moses/CMakeFiles/moses.dir/moses/moses_main.cc.o
In file included from /home/myname/opencog/moses/moses/moses/moses/../metapopulation/metapopulation.h:42:0,

             return 1 - std::pow(this->prod, 1.0 / count(args));

This looks like a simple C++ error, and should be easy to correct, unless I'm missing something vital.

Thanks for your report!
