I did see it, I just hadn't had chance to reply (the other install-related
thread is getting large and I do have a day job :)).

But what about your curious semi-knowledgeable user who downloads GCC from
the website as binaries, or selects one from cygwin. You can't say Boost
supports installing gcc-3.2 and 3.3, but if you have 3.3.1 then you'll have
to build the libraries manually.

Have you seen my latest post on the other thread. The method I proposed
supports both pre-built libraries and a guided build to give the user the
choice. It also opens up the setup program to use cases such as:

1. I have a copy of Boost 1.32 on my machine that I am just using headers
for (Boost.Build is too complex!). Now I want to use Boost.RegEx on gcc-4.0,
but that requires me to use Boost.Build.
   SOLUTION: run setup.exe; select your local Boost distribution,
Boost.RegEx and gcc-4.0; build the libraries and check the results in a
friendly summary.

2. I want a standard version of Boost for a supported (w.r.t. pre-build
libraries) compiler and don't care about bandwidth as I have a decent
   SOLUTION: run setup.exe; select next for all options (will download
pre-build libraries)!

3. I want to get the latest CVS version of Boost.
   SOLUTION: run setup.exe; select CVS for download option; use defaults
(will build the libraries, not download).

4. I want a standard version of Boost, but have a slow/limited internet
   SOLUTION: run setup.exe; select defaults except for generating the
libraries (select 'build all').

Presto! Everyone is happy :)
