games/flightgear build failure

Hi,

On -current at  least, games/flightgear fails build:
......

.....

because /usr/pkg/include/boost/config/detail/select_stdlib_config.hpp
also includes a file with the same name, there is one in the top
directory of the package and this top directory is ahead in the
include search sequence.

To get the package built, I had to rename its 'version' file to
'fgversion' and change the coresponding line in the CMakeLists.txt
file:
....
