Bizarre Xcode permissions problem

[royliu@…]

I recently upgraded to Xcode 4.5.1 (along with Command Line Tools), and I have been getting the following.

error: couldn't create directory /var/folders/d_/bpdgfp1n3z97kh7wl3m79lj00000gp/C/com.apple.Xcode.502/SharedPrecompiledHeaders/QuickLookPlugin-Prefix-gbcgytovtbjwlkfdpkqeuzxvcyey: Operation not permittedwarning: unable to open file /var/folders/d_/bpdgfp1n3z97kh7wl3m79lj00000gp/C/com.apple.Xcode.502/SharedPrecompiledHeaders/QuickLookPlugin-Prefix-gbcgytovtbjwlkfdpkqeuzxvcyey/QuickLookPlugin-Prefix.pch.dia for serializing diagnostics (Error opening output file '/var/folders/d_/bpdgfp1n3z97kh7wl3m79lj00000gp/C/com.apple.Xcode.502/SharedPrecompiledHeaders/QuickLookPlugin-Prefix-gbcgytovtbjwlkfdpkqeuzxvcyey/QuickLookPlugin-Prefix.pch.dia') [-Wserialized-diagnostics]

I've observed this problem in the build processes of transmission and gimp-app. Please find the build log for transmission attached. It if helps, I am on 10.8.2.

I experienced the same with graphviz-gui-devel, the /var/folders/* paths seemed to have correct permissions, macports:macports owned from /var/folders/*/* downward. In my case changing working directory to $worksrcdir and manually issuing the build command succesfully built the package.

I reproduced the same issue several times with cleaning between port build runs, after a certain clean it built and I cannot reproduce anymore. Yes, this is weird.

edit: I still have the issue, it happens in destroot phase while I was searching it in build phase. I'm attaching log as well.

This is probably caused by sandboxing introduced in macports trunk.

Updating base to r98904 solved my issue.

Assuming the version field was set wrong then.
