Develper Tools

Hello, has anyone been able to successfully install XCode 3.0 via instadmg? They are package installers, but they are pretty complicated (lots of pre-flight, post-flight, etc). They also require that I am booted off of the target drive, which is obviously not the case on instaDMG. I have used logGen and pkgGen to create my own package, but I fear that this is not perfect. I would rather use Apple's stock installers if possible. Someone suggested opening the package w/ an editor, and remove the volumecheck() method so it doesn't require the boot volume. If anyone has done this successfully, let me know. -Jeff
