GC/Wii Compatible libpng?

I'm currently doing some development for the Wii, but to develop my programs I write and test them on a Gamecube emulator and then recompile/extend for Wii system/controls. Now this has been all well and good for the Freetype development that I've done thus far since there exists a compiled library for both the Gamecube and Wii.

However, since I'm looking to make the move into more graphics-based processing and would like to begin with the community-standard PNG support. Now, with the current release of devKitPro there is a Wii-specific release of libpng, however there is not a corresponding one for the Gamecube. So, to conclude my entirely too-long tale of woe - Does there exist a Gamecube-compiled libpng library so that I may continue with my development methodology?

You should be able to compile Wii binaries and run in emulators like Dolphin already.
You can't run it on your real Wii?

if you want you can reuse this package i prepared for scummvm and hbc:

[static.hackmii.com]

Tremor rev 15592
expat-2.0.1
flac-1.2.1
libpng-1.2.34

the binaries are usable for gc and wii, there is no wii dependent code in it

Thanks GizmoTheGreen. Shows how up-to-date I am with the scene. Last time I checked Dolphin didn't have Wii support, but it looks like I have a new emulator to test under now other then gcube.

Thanks to you too dhewg. I'll probably go ahead and install those libraries into by build path in case I ever want to go back and make my code cross-platform compatible.
