The cvs should contain a folder called "patches" which contains a the patch
to vigra 1.2.0. I'll also send you a complete, already patched version of
vigra.

The diff's can be applied with the patch command, usually with

cd dirwithfilestopatch
patch < the_patch_file

Ok, I'll take a look.

Just do a "cvs update" in the top level hugin directory, or use a similar
function in Xcode.
