怎么将python安装包打成rpm包？

从官网上下了python3.1.2的tar.bz2包，里面有spec文件，用这个来打rpm包老是出错。有知道怎么打的大侠不？
没次到这就出错：
+ echo '#!/usr/bin/env python3'
+ echo 'import os, sys'
+ echo 'os.execvp("/usr/bin/python3", ["/usr/bin/python3", "/usr/lib/python%{libvers}/idlelib/idle.py"] + sys.argv[1:])'
+ echo 'print "Failed to exec Idle"'
+ echo 'sys.exit(1)'
+ chmod 755 /var/tmp/python3-3.1.2-root/usr/bin/idle3
+ cp -a Tools '/var/tmp/python3-3.1.2-root/usr/lib64/python%{libvers}'
+ rm -f mainpkg.files
+ find '/var/tmp/python3-3.1.2-root/usr/lib64/python%{libvers}/lib-dynload' -type f
+ sed 's|^/var/tmp/python3-3.1.2-root|/|'
+ grep -v -e '_tkinter.so$'
