What about it? You need to have ERL_TOP explicitly set only when you
are doing a custom invocation of "make" in some leaf of the OTP tree
during a build process. Once you have OTP installed (such as using the
"config --prefix="..." option, "make" and "make install"), you don't
need ERL_TOP set.

Yes. Or else use the PATH environment setting as Dominic suggested.
