Permission problem

[Rav]

Hi,
 
When I am builiding a rpm and installing the rpm in a linux machine, the files that are part of this rpm is having permission as follows.
 
[root at devbsc2 backup.plugins]# ls -l
total 4
-r--r-----  1 root root  541 Jul 28 11:56 bsc-hardening.plugin
-r--r-----  1 root root  677 Aug  7  2008 ipaccess-base.plugin
-r--r-----  1 root root  261 Aug  7  2008 ipaccess-common.plugin
 
But if I build the same rpm in a different machine, then the permissions vary as follow.
 
-r--r--r--  1 root root  541 Jul 28 11:56 bsc-hardening.plugin
-r--r--r--  1 root root  677 Aug  7  2008 ipaccess-base.plugin
-r--r--r--  1 root root  261 Aug  7  2008 ipaccess-common.plugin
 
Could someone explain why the problem in the first machine. Any way to fix this. Your reply will be appreciated.
 
Regds,
