I am trying to install xcode 4.1 with lion. Apparently at 3/4 of the installation problem, it says to close itunes, which is not open. How can I fix the problem?

This is a widely-reported bug in some App Store installers. It sees the iTunesHelper process and displays this error, even though that process is not controlled by the user.
You can open Activity Monitor (in /Applications/Utilities), find the process and kill it with the Quit Process button in the top-left corner.
You can also instead open Terminal (also in /Applications/Utilities), enter the following line and press enter to kill it.
killall iTunesHelper
You can control or right click to show package contents and run only select portions of Xcode 4.1.
The program Pacifist will let you look into the packages to see what each contains.
The installer has changed to remove the options - it's all or nothing. If space is tight on your boot drive, you will have to either install to another volume and move parts back or temporarily free up enough space to install and clean out what you don't want to keep.

Best Answer
Use Activity Monitor, and locate the iTunes Helper process and kill it. As per an Apple support discussion and several other sources.
Update: The latest Xcode installer has been fixed and this should not be an issue now.
