First you need to read UPDATING, and then use the build.sh script.

I just did this the other night (two nights actually) and it went without
so much as a hitch.  Occasionally you will have an error with the build,
but doing something listed at the bottom of UPDATING will sort it out.
I needed to upgrade make by hand, and then my includes, and then
the rest fell into place.

I did a full etcupdate and merged my files, and then rebuilt 1.6 while
running 1.6 afterwards.  No worries.
