reconciling defvars - using package manager

[Jambunathan K]

The question concerns `org-inlinetask-export-templates' which is
defvared in `org-inlinetask.el. 

In org-7.7 which is bundled with Emacs pretest the variable has some
value say v1.

In the daily builds, say org-20111009.tar, the above variable has a
different value say v2. 

Now when I upgrade it to the daily build I find that the variable stays
at the 7.7 value. As a user I was expecting that the variable reflects
the org-20111009 setting.

I am wondering whether replacing defvar with defcustom will improve the
situation here

or 

are there any other workarounds.

TIA,
Jambunathan K.
