[Starkit] Tclkit-darwin-univ-aqua on 10.3.9?

[Joey Mukherjee]

Sorry for crossposting to two lists, but I think this a Mac specific  
problem related to the Tclkit binary available from JCW's site and  
I'm hoping one of the groups might have an answer.

The TclKit binary that I am wanting to use is tclkit-darwin-univ- 
aqua; however, when I try to use this program on a 10.3.9 system, I  
get the following error:

./tclkit-darwin-uniq-aqua undefined reference to _OSSpinLockLock  
expected to be defined in /usr/lib/libSystem.B/dylib .

Is there an easy solution to this problem?  I'm hoping I can update  
something on the 10.3.9, or another version of the tclkit binary.

Thanks,
Joey
