You should create a new plist that inherits from one of the provided plists (see 10B504.plist for how it inherits fro 10A432.plist). Then just add the differences to your plist. In order to see CoreServices.framework during the build, you need to pass the "-nochroot" option to darwinbuild (which means nothing in BuildRoot will be used) or copy CoreServices.framework into your BuildRoot/ (this is the best approach).  If you need to reload a plist, use "darwinxref loadIndex <path-to-plist>".

I tried to force addition of the headers with "darwinbuild -header dyld" and "darwinbuild -header libdyld" but both fail.

That header is provided by libdyld. Try "darwinbuild -load libdyld" to load the full libdyld root. Doing "darwinbuild -header libdyld" says "build the installhdrs phase". Using both "-load" and "-header" says to "load the headers root", which would look like "darwinbuild -header -load libdyld".

This works for me, note that xcodebuild is passed a -target option:

# darwinbuild -target=PIV Tokend
zlib                 -> bf9a63cca042bf6656be18a883ac0edd1f33fc35
xcodebuild install -sdk Darwinbuild_10C540_20091207070452 -target "PIV" "SRCROOT=/Users/wms/darwin/10C540/BuildRoot/Sour...
