Rick is right. We are not going to distribute wxWidgets binaries. There are just too many options: static lib, dll, unicode, non-unicode, wx2.4.2, wx2.6, monolithic, etc.
Regarding devpacks:
I have already written the decompression code for devpacks. All that's left is make a gui for it. I don't know, though, if it will make it in the next release.
