Netscaler (Citrix) SSL VPN on MacBook Pro?

Has anybody gotten a Netscaler SSL VPN session to work on a MacBook pro?

After I authenticate with a cryptocard the service downloads the "clientless" SSL VPN java agent.

The popup window titled "secure remote access session" looks like it is running, then the java logo is replaced with a red "X".

Safari java console shows an error message:

java.lang.UnsatisfiedLinkError: /private/tmp/libMacProxy.jnilib:

This looks like either:
1. Java 1.5 runtume incompatibility w/ 1.4 code, or
2. Intel duocore incompatibility

My company IT says they don't support mac's, so I'm hoping somebody can here can help.
