This only occurs on the Fedora 15 build servers, but works on RHEL5 & RHEL6.
It fails on Fedora 15 i386 & x86_64.  

I can build the same package natively on a Fedora 15 server ok with this spec and tarball, and all of the other builds worked.  

What is wrong here?   Is there an odd spec file issue or is it the Fedora 15 environment?

Reproducible: Always

Steps to Reproduce:
1. Use the ipmiutil-2.8.4.tar.gz and current ipmiutil.spec
   For more details, see 
  https://build.opensuse.org/package/show?package=ipmiutil&project=systemsmanagement
2. On Fedora 15, run rpmbuild -ba
Actual Results:
