Are you trying to use SDKs in a project that has legacy (Jam-based) targets?

Here is a snippet of the build output from another of our projects with this problem:

Ld /Volumes/UserDisk/joar/5.2/Orc.app/Contents/MacOS/Orc normal ppc

cd /Volumes/UserDisk/joar/Documents/CVSROOT/Orc5.2/clients/Orc

setenv MACOSX_DEPLOYMENT_TARGET 10.2

setenv NEXT_ROOT /Developer/SDKs/MacOSX10.2.8.sdk

/usr/bin/gcc-3.3 -o /Volumes/UserDisk/joar/5.2/Orc.app/Contents/MacOS/Orc -L/Volumes/UserDisk/joar/5.2 -L/Volumes/UserDisk/joar/Documents/CVSROOT/Orc5.2/clients/Orc -L/Developer/SDKs/MacOSX10.2.8.sdk/usr/lib/gcc/darwin/3.3 -F/Volumes/UserDisk/joar/5.2 -filelist /Volumes/UserDisk/joar/5.2/Orc.build/Orc.build/Objects-normal/ppc/Orc.LinkFileList -lorc -framework AppKit -framework ApplicationServices -framework Carbon -framework Cocoa -framework DirectoryService -framework ExceptionHandling -framework Foundation -framework OpenGL -framework OrcAdditions -arch ppc -all_load -Wl,-syslibroot,/Developer/SDKs/MacOSX10.2.8.sdk

ld: warning NEXT_ROOT environment variable ignored because -syslibroot specified

The NEXT_ROOT method of specifying an SDK is, as you might guess, a hangover from the NeXT days, and has been replaced in more recent versions of gcc with the more manageable -syslibroot flag. But for 2.0 the ld linker for gcc3.3 still requires NEXT_ROOT, so we have to pass both. The warning is innocuous and can be ignored for gcc 3.3, and is absent in gcc 4.0.
