The old scratchbox ("sb1") uses chroot, sb2 does similar tricks  
without chroot. The result should be that you are not forced to work  
in "chroot jail", but still get replacements for /usr/include and  
other essential directories and tools.

If you are compiling for maemo, then try the Maemo SDK+ beta from http://maemo-sdk.garage.maemo.org/

And that is useful even if you are not compiling for maemo; the tools  
are pretty much neutral when the target distribution is considered. It  
is the rootstrap (root fs) which contains the "maemo personality". If  
someone wants to create a completely new SDK for something else than  
maemo, I'd recommend starting from the SDK+ project and figuring out  
how to create a suitable root fs in the first place. The set of tools  
can be trimmed later.

Also note that "configure" and "make" are not the only tools that  
you'll need when you are cross compiling packages, the underlaying  
truth is usually really much worse... What we now have in the maemo  
mode of sb2 and what is included in SDK+'s tools collection (which  
uses unmodified tools from debian "etch" and contains about 100 other  
tools than just "make") is the result of our experiments about what is  
needed for cross-compiling various OSS packages (and maemo packages,  
too, of course). So, the "maemo" mode is not really limited to  
compiling for maemo only, it is more about compiling existing, complex  
packages..
