working with obj-c under freebsd!

[Mayuresh Kathe]

i had asked this question before and was advised to install
the gnustep framework before trying out obj-c development
under freebsd.

finally got the whole thing installed and tried to compile
the following simple objective-c program.

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{
	@autoreleasepool {
		NSLog (@"Programming is fun!");
	}
	return 0;
}

the compiler options used were as below;
clang -fobjc-arc main.m -o prog1

the compiler threw up the following error;
main.m:3:9: fatal error: 'Foundation/Foundation.h' file not found
#import <Foundation/Foundation.h>
        ^
1 error generated.

what can i do to get the above resolved?

thanks,
