build 199 and xcode

Damn, I was running "InstaDMG version 1.5rc2 (svn revision: 197)" and it started to install Xcode and I got an xcode error. I was trying to take a screen shot of the error and I accidentally hot return, so the dialog went away. I can't find the error in the logs, but it was something about trying to install xCode in a non-empty directory. Anyone else seen this?
