Great, I've never heard of XBuild but I assume that it is a frontend to the
standart gcc toolchain. Btw. which version of gcc does OSX use?

I'm in the progress of compiling the Win32 version of hugin with wxWindows
2.5.2. (It compiles, but crashes when loading the first image...)

I've tried to fix this in the current cvs (beware, the anonymous cvs might
be delayed up to one day). I wonder how you could compile the standalone
vigra, since it should contain the same code.

I needed to extend vigra a little bit, please apply the patch in the new cvs
version, patches/vigra_typetraits_extension.diff, and recompile.
