The current stable userlands don't compile in my environment.
First, libselinux-1.34.7 throws a compiler error which seems to be caused by a gcc bug:

It could be solved by removing -z,defs from the src/Makefile. I don't know the consequences but it works.

Second, the policycoreutils-1.34-6 won't compile because of a missing header file, which is not existent in my environment:

That's why I'm using the old sources. They work.

kernel version is 2.6.16-omap1
How do I find out the policy version?
