This question has been posted already but never answered, I only need an answer if there has been a fix for this. I have looked over the entire forum and have not run across anything yet. I am running mac osx 10.6 with Parallels Desktop 6 and get an error every time i try to install guest tools. I have installed kernel source via prepare-kernel-sources and that did not fix the issue. Please let me know if there is a fix or if it's not worth my while trying to install, thank you .
