I saw the below reply from Michael at
http://www.nntp.perl.org/group/perl.makemaker/2010/10/msg3225.html
but did not know how to reply to it. So I am sending my reply through my mail
account again.
>> Then use newgrp to change to that group before installing modules.
Even if all people installing perl modules belong to the same group, there can
be only one owner for the .bs file. So chmod statement in MM_Unix.pm would
still fail for all people except for the owner as one needs to be the owner to
change permissions of a file. Let me know if I am missing something.

Having your library files be writable by anyone on the system is a security
hole, anyone who gets minimum access can install a trojan, so the chmod is
doing the right thing.
Simplest thing to do is to put all the users who can install Perl modules into
the same group. Then use newgrp to change to that group before installing
modules.

The following code in ExtUtils::MM_Unix is doing chmod 664 on .bs file. This
means that two different users cannot do installation as if one user if the
owner, then the other cannot do chmod on it. Is there any solution to this? Or
am I missing something?
# As Mkbootstrap might not write a file (if none is required)
