Reviewing these I cannot see how this cannot be solved by replacing
'/opt/csw' by the "prefix" macro. What I'm missing? Aside of tweaking a
little bit mgar.

IMHO being able to build in another prefix is an interesting exercise,
but not vital, and it will eliminate branches in our recipes such as
'NIM'.

However, what's more interesting is to be able to rebuild the complete
set of packages from scratch. BTW, you have given this as a rationale.

Being able to rebuild from scratch is possible with average but dedicated
work. The main obstacle, from my stand point, is the missing
documentation for making a build farm. This brings us to another thread
which is for the moment moribund.
