I get the following errors while doing a Build (iPhoneDistribution)

#import <libxml/tree.h>

No such file or dir

The same error is not thrown when using Simulator/Device onwhich the app runs fine..

What is the cause of this error? Please help me.

You should check your configurations to make sure that they all have the same set of header search paths.

In xcode 3 get info on your target and select build settings. In xcode 4, select the project in the navigator, then build settings and target. type "header search" into the filtering text box at the top. There will be an entry for Header Search Paths. Make sure that all the build configurations have the same set of search paths.
