Take note that the above line doesn't enforce any order. It just says
that, to "make all", you need pure_all and manifypods. Nothing keeps any
make (or any human!) from doing them in any order or in parallel.

If manifypods depends on pure_all, there must be a dependency on it,
otherwise it doesn't work.

Another way to view this: if you invoke make with "make manifypods", you
wouldn't expect it to depend on "pure_all".

So if there is no dependency (explicit or not) from manifypods, and
something in manifypods needs a built module, the Makefile is broken.

First of all, are you sure you have no other Gtk2.so installed anywhere?
I only found out about this because I didn't. Builds work perfect for me
as long as I have a installed Gtk2.so...

Diving into the Makefile, the only dependency I see is:

   build/stock_items.podi: tools/podifystockitems.pl

And sure enough, running "make build/stock_items.podi" fails because
Gtk2.so is not available.

That _looks_ to me (not knowing much about the Gtk2 Makefile generation),
as if there needs to be a dependency on the linked module there or
somewhere else. At leats with my perl and my system, no other dependency
is generated.

Then you had luck or a different Makefile, as nothing ensures that this
order is used (or you had an installed Gtk2.so).

At leats in my Makefile, there is no such dependency. In fact,
the only depency I see is on build/stock_items.podi and points to
tools/podifystockitems.pl. tools/podifystockitems.pl does not depend on
anything in my Makefile.

And I can't see where the dependency should come from. Looking at the
Makefile.PL, that part is clearly manually created, so I don't think
differences in ExtUtils::MakeMaker could account for this.
