CageFS command not working for user

I have flvtool2 installed on the server. Path to binary file location was added in file /etc/cagefs/conf.d/vshare.cfg

[root@server22 ~]# cat /etc/cagefs/conf.d/vshare.cfg 
[vshare]
comment=vShare Youtube Clone Requirements
paths=/usr/bin/ffmpeg, /usr/bin/mencoder, /usr/bin/mplayer, /usr/bin/flvtool2, /usr/bin/lame, /usr/bin/yamdi, /usr/bin/qt-faststart, /usr/bin/MP4Box, /usr/bin/mediainfo, /usr/bin/neroAacEnc
[root@server22 ~]# 

The binary program works properly when running as root, but it fail when switching to a user that use CageFS.

[root@server22 ~]# /usr/bin/flvtool2 -V
FLVTool2 1.0.6
[root@server22 ~]# su - socialwe

[socialwe@server22 ~]$ /usr/bin/flvtool2 -V
:1:in `require': cannot load such file -- rubygems.rb (LoadError)
from :1:in `'
[socialwe@server22 ~]$

The problem is fixed by editing file /etc/cagefs/cagefs.mp

vi /etc/cagefs/cagefs.mp

Add following lines

!/usr/lib64/ruby/
!/usr/share/rubygems/
!/usr/share/ruby/
!/usr/local/share/ruby/

Now remount cagefs with

cagefsctl --remount-all
