iOS build failure

[animeshk-1968]

iOS build works fine when I debug using a simulator. When I try to debug on my iOS device (iPhone 6+), I get an error:

Looks like a problem with the png library not working with iOS for some reason. The png library was updated in 3.2. Is this the first time you've tried debugging on your phone? Can anyone confirm that it works for them on an actual iOS device? This might take some research to solve.

In the past, I've had no problem building Torque2d and launching it on an iPhone, but I do not believe I have ever run it on an iPhone 6+. I was wondering if this was a 64-bit issue: has anyone run this on an iPhone 5s or later?

I have built and deployed to an iPhone 6 and 6s using 1 or 2 versions of
T2D back and iOS 9.1. The newest head was not building due to OGG problems
and some other things I didn't have time to better understand... and I
didn't want to add iOS 9.3 into the mix just yet. Will try to get the
build process verified this weekend when I have more time.
