Build Notes
ipmitool-xcat is architecture specific and needs to be built separately on x86_64 and ppc64le

RPM Option #1 Run the script bldipmi.pl
1) yum install openssl-devel rpm-build autoconf automake libtool ncurses-devel readline-devel
2) Update "release" variable in "bldipmi.pl" if generating a new version of the RPM
3) Run "./bldipmi.pl" which creates:
     /tmp/build/<os>/<arch>/ipmitool-xcat-<version>.<arch>.rpm

RPM Option #2 Use the manual steps listed below:

1)   Download ipmitool-1.8.11.tar.gz from https://xcat.svn.sourceforge.net/svnroot/xcat/xcat-dep/trunk/ipmitool/ipmitool-1.8.11.tar.gz to /tmp/ipmitool directory.
2)   cd /tmp/ipmitool
3)   gunzip ipmitool-1.8.11.tar.gz
4)   tar xvf ipmitool-1.8.11.tar
5)   Copy ipmitool.spec to /opt/freeware/src/packages/SPECS/
6)   tar cvf ipmitool-1.8.11.tar ipmitool-1.8.11
7)   gzip ipmitool-1.8.11.tar
8)   Copy ipmitool-1.8.11.tar.gz to /opt/freeware/src/packages/SOURCES
9)   Copy ipmitool-config.h.in.patch, ipmitool-imbapi.patch , and ipmitool-ipmievd.patch to /usr/src/packages/SOURCES
10)  cd /usr/src/packages/SPECS
11)  Run "rpm -bb ipmitool.spec", which creates:
             /opt/freeware/src/packages/RPMS/ppc/ipmitool-1.8.11-1.aix5.3.ppc.rpm 

DEB Option #1

1) git clone https://github.com/xcat2/xcat-dep.git
2) apt install dpkg-dev debhelper libssl-dev quilt libreadline-dev
3) cd xcat-dep/ipmitool
4) ./make_deb.sh
5) Will generate file ipmitool-xcat_<version>_<arch>.deb file in current directory
6) Use debian/changelog file to update release version

NOTE #1 
HOW TO CREATE THESE PATCHES 
1) cd /tmp/ipmitool-1.8.11
2) mkdir a (this directory contains the original file)
3) Copy original file to "a" subdirectory
4) Repeat above for directory "b" (this directory contains the changed file)
5) Copy changed file to "b" subdirectory
6) cd /tmp/ipmitool-1.8.11
7) diff -uNr a b > ipmitool.patch

NOTE #2
ENABLE THE SSL
Before running the build operation, the openssl-devel should be installed on the build env to make sure the ssl can be enabled for the generated ipmitool package.
You can run the 'ldd ipmitool' to see whether the 'libcrypto.so.x' has been added as a dependency to check whether the ssl has been enabled.


Note #3
On RHEL 7.1 ppc64le, probably because of the beta version of toolchain, needs to add "--build=powerpc64le-redhat-linux-gnu" with the ./configure in ipmitool.spec
