Make all gets the same environment as make install (assuming you do it in the same shell). But if you sudo make install, the environment may be different - it may not inherit everything from your environment.

I advised the user to "sudo -s" and ten setup the compiler environment and then run make install.

Sent from my phone. No type good.
