SCons build, help needed

[Karel Miklav]

I'm trying to make a port of the latest Blender with the SCons build. 
The scons command in the do-build target in bsd.scons.mk is expanded in:

/usr/bin/env /usr/local/bin/scons \
   CCFLAGS="-O2 -fno-strict-aliasing -pipe" \
   CXXFLAGS="-O2 -fno-strict-aliasing -pipe" ...

Which gives an error:

scons: Building targets ...
Compiling ==> 'SND_DummyDevice.cpp'
cc1plus: error: invalid option argument `-O2 -fno-strict-aliasing -pipe'
scons: *** [/usr/home/ ... /SoundSystem/dummy/SND_DummyDevice.o] Error 1
scons: building terminated because of errors.

The problem is in the CCFLAGS variable; it is passed to the compiler as
a whole, white spaces between individual flags are ignored. Should I 
rewrite variables in some other syntax or what?

Thanks.
