After a couple weeks' worth of searching, finally found out the commands to setup Network connect to work with my Mac at home, instead of lugging around all the stuff from work:
- install the Network Connect client.
- run it once. It *will* barf. Just clean up with a paper towel
- Drop into bash, and run the following:
bash-3.2# chmod 755 /usr/local/juniper/nc/6.*/
bash-3.2# mkdir /Applications/Network\ Connect.app/Contents/Frameworks
bash-3.2#
And that's IT!
