I was hoping that there was some self-contained summary. The admin
manual specifically suggests to look at two external sites that don't
seem to provide any relevant information, which is a worry because it
implies that the information given there is not complete.
I have a third-party 32-bit package (an Epson driver) and was hoping
there was some easy standard way to create an environment that will
build it without having to modify the package. Adding flags involves
understanding how its build system works and it also seems a bit
perverse to have to give a 32-bit only package knowledge that it is
being compiled in a 64-bit environment. It seems to me that this would
be a very common situation and so might have a FAQ answer.
I also have some questions about libraries that I was hoping such a
document would resolve. I'll submit those separately if I don't manage
to resolve them with a search.
