	CMAKE_ARGS+=	-DCMAKE_COLOR_MAKEFILE=off

I put this in /etc/make.conf:

# grep COLOR /etc/make.conf
CMAKE_ARGS+=    -DCMAKE_COLOR_MAKEFILE=off

but building e.g. science/paravew in script(1),
I still get corrupted output, e.g.

In file included from /usr/include/c++/4.2/backward/strstream:51:
^[[1m/usr/include/c++/4.2/backward/backward_warning.h:32:2: ^[[0m^[[0;1;35mwarni
ng: ^[[0m^[[1mThis file
      includes at least one deprecated or antiquated header. Please consider

Or is this nothing to do with colour?
Then how can I get rid of these special
characters?

Thanks

Anton
