X-Code not able to share with team

I am building a C++ game with my team and we use Perforce as a repository. I loaded it into Perforce and my Lead Programmer downloaded it and went to open the project. It loaded and opens correctly but he is unable to compile- the compile fails and he gets a disk permissions access denied. I dont have a copy of the message but that is the general idea.

Any help on this would be great- I have no idea what permissions I need to change PLease help

Do any changes need to be made before the package is created or can you make the changes so people can share it and edit the code after the project has been created?
