Having two perl (and two anything else) is first step to maintance hell.
We have virtualization, chroot.... for such experiments.

How does it differ from half system using one perl and half using second 
perl? One pain or second pain?

It comes to question, who is  our target user. If this was asked on 
Ubuntu forum I would argue as loud as possible for /usr/bin/perl, 
because possibility that somebody will make some mess in /local or ~ 
/bin is high, and env will make it worse.
But we are Fedora, so I will not argue about it here since, I have to 
admit, I do not now who is target user of Fedora.
