I believe this different than the original inquiry which was about showing
progress during the build including progress of a single package.

I say it is not possible because there are too many variables: different
operating systems, different compilers, different dependencies (native
versus pkgsrc for example), different supplementary tools (like sed, awk,
grep). I don't see how we can estimate how long something takes. And
building some database of known build times won't scale well. Even my AMD
K6-400 machines builds many packages faster than my 1000Mhz+ machines.
