新的plone安装失败，出现此错误：
Copying buildout skeleton
Fixing up bin/buildout
Building Zope/Plone; this takes a while...
Buildout returned an error code: 126; Aborting.
Buildout failed. Unable to continue
Installation has failed.
See the detailed installation log at /home/adrigen/Downloads/Plone-4.3.2-UnifiedInstaller/install.log
日志说
/bin/sh: 1: /home/adrigen/Develop/Plone-4.3.2/zinstance/bin/buildout: Permission denied
文件夹权限说
drwxr-sr-x 7 plone_buildout plone_group 4096 Nov 21 19:01 Plone-4.3.2
这是我运行带有和不带sudo前缀的安装的时候。问题可能在这里？
