Version 1.0 won't run on Mac OS X 10.5.8 about hoxchess HOT 2 OPEN

So far, I tried to build HOXChess and its AIs as 32-bit (x386) binaries but 
that did not help. I will do more 
research on this specific error again... 

I managed to get HOXChess and these AIs (except AI_HaQiKiD) working on my MBP 
running OX 10.5.6 by:
1. Download the HOSChess version for Mac OS and install the application
2. Download the HOSChess source code, decompress it
3. Open Terminal, go to each AI folder (inside "hox_Project/plugins") and run:
    make -f Makefile.osx
4. Copy all the resulted AI_*.dylib files to 
"HOXChess.app/Contents/SharedSupport/plugin
s/"

For the success of step #3, you need g++ already installed on your Mac.
