Yes, you're right, but if I left it as follows:

main_env=Environment()
main_env['ENV']['PATH']=os.environ['PATH']

I get the problem related to "no compiler found".
By the way, I can make scons be aware of where my compiler is by doing this:

main_env=Environment()
path = ['/OVS/software/bin', '/bin', '/usr/bin']
main_env = Environment(ENV = {'PATH' : path})

Yes,  that's what I thought! But the fact is that I have "/OVS/software/bin"
in my PATH (and I can see that it is the compiler being used, thanks to
"which")!

Yep. I agree. But it is already done ;)

Cool!
