Ah ok, that makes sense now. It's possible that Kry built the Mac binary on a Tiger machine and it therefore does not run smoothly on 10.3. For this reason, I build all my CVS binaries on 10.3 so that they are compatible with both 10.3 and 10.4.
Unfortunately, I have to leave in 30min and won't be back until very late tonight, but if things have not been worked out until then, I'll build a 2.1.0 binary on my 10.3 then and post it here.
