What I think is happening is while building
sysvinit with the SELinux patch, sysvinit is looking
in /lib for libselinux(but could be wrong) but libselinux is in
/lib64.
(here's my excuse as a newbie:)
  part of a pain when building an x86_64 multilib is building
everything to point to lib64(pure64 with the soft link
lib64 -> lib makes life so much easier).

I'm going to look at that patch and see how it tells
-lselinux -lsepol to find the libs.
(if this is the case then I must admit I am a real
newbie, and apologize for the confusion).
