This is the install script I am using. It might be a starting point  
for you:
#!/bin/bash
CONTEXTVERSION="beta"
CONTEXTDIRECTORY=$HOME/TeX/context/$CONTEXTVERSION
rm -R $CONTEXTDIRECTORY
mkdir -p $CONTEXTDIRECTORY/tex
cd $CONTEXTDIRECTORY
ln -s $HOME/Library/texmf tex/texmf-local
#cp -R $HOME/Library/texmf/* tex/texmf-local
curl -o first-setup.sh http://minimals.contextgarden.net/setup/first-setup.sh
sh ./first-setup.sh >first-setup.log
cd tex
echo "installation context $CONTEXTVERSION minimals done"
