I'm trying to get started with making the latest clone from the git repository and I get the following error:

[bpm]$ git clone http://git.fedorahosted.org/git/scap-security-guide.git scap-security-guide

[bpm]$ cd scap-security-guide/RHEL6/

[bpm]$ make all

I've a fedora 18 , x86_64 installation. 

Any ideas?
