At line 232 of /packaging/RHEL/samba.spec, the 'for' list is broken to two lines with an extraneous line feed. This leaves 'libnetapi' on a line by itself, which results in a syntax error and a build failure.
Will attach patch to fix...
Created attachment 3680 [details]

This has already been fixed meanwhile.
Thanks for reporting!
