I am coming to this a little late, but what is the problem building 
inside MacPorts?  Is there a requirement that build happens separately 
from install?

cppdom is definitely not designed to do that.  It has been designed to 
follow a fairly common best practice of having one command that does a 
complete build and install and does it every time (it is also 
recommended to have this run the testsuite, but we don't have that in 
there yet. :).  That way developers are *always* using the same build 
paths that are used by users and packages to install the tool and there 
are no special hoops to jump through to install or package the 
software.  Just one magic button that will take you from source to 
happiness. I hadn't heard of this causing problems before, so I am 
interested in hearing more here.

If you really need the build and install separated, you could do 
something like this:

- Build
   - call scons without a prefix setting
- Install
   - call scons with a prefix setting

This will end up "installing" cppdom in the development directories on 
the first call, but it should work for you.
