Which source are you using? What OS? Any other info that you think might be helpful.
Edit: I just tried it out here and didn't see anything like that ... seems to be saying some source/header files not found?
I'm on Xubuntu 13.04. I am using the most recent Namecoin code (in the namecoin-qt branch) as of now. Here is the latest entry from 'git log':

Merge branch 'namecoin-qt-snailbrain' into namecoin-qt
Thank you.
snailbrain ^^ ??
PS : as I said previously, I suggest your coder puts namecoin-qt.pro in the top dir (not project) and stops using all those "../" paths since you do not know how different OS and qmake versions will interpret that on all possible platforms ... or simply put, just follow the bitcoin-qt dir/build structure.
I have created a pull request that does that. It also includes the easywinbuilder directory but you can simply delete it if you don't want it to be included.
