I am having a weird issue with the Programming is Fun example on the first few pages of chapter two. Please help!

I run the program, and it builds/runs with no issue, but the all output displays the following:

error: failed to launch ' /Users/rrusnac/Library/Developer/Xcode/DerivedData/HelloXcode-bjizacconqitzffbzlhsurwvrpfo/Build/Products/Debug/HelloXcode' -- invalid host string: 'localhost'

I can find the file it is looking for, and when I open it, it does display the program as it was intended.

I am using Xcode 4.3.2 (4E2002) and Mac OS 10.7.3.
