OpenOCD http server problems

Can someone help me here?

I wanted to try the OpenOCD http server functionality. However, opening its URL results in this error:

Runtime error, file "/usr/local/share/openocd/httpd/index.tcl", line 147:
invalid command name "encode" 
In procedure '' called at file "httpd.c", line 292

I am on a Linux system (Ubuntu 9.10) and I have the TCL 8.5 shell set as my default (I have also tried with 8.4).

I have installed tcllib, as well.

My OpenOCD version is

Open On-Chip Debugger 0.5.0-dev-00053-g5e78ddc (2010-03-04-18:05)
