Hello !
After installing OS X Mavericks, i have a problem to compile my project, and to compile the lastest version of introjuicer.
I have read some posts about it, that explaining that it is necessary to change the OS X deployment target, but i have tried all taget like 10.4, 10.5 ... but this does not solve the problem.
I have SOLVED the problem while I was writing this message 
Juste change the "Base SDK" in project option, with value "Lastest OS X", maybe this message can help someone .
