To build a package one need to run autoconf and then create a tarball of the
RHEL4 directory so that the content is like this:
$ ls -1 ipa-client-0.99.0
aclocal.m4
AUTHORS
autom4te.cache
ChangeLog
configure
configure.ac
COPYING
INSTALL
install-sh
ipachangeconf.py
ipa-client-setup
ipa.conf
Makefile.am
Makefile.in
missing
NEWS
README
setup.py
the spec file will then be able to build a package for RHEL4
