Commander-S -- where are handle-signal-default and ignore-signal defined?

Apparently this is the place for Commander-S support.  I was fascinated
to find out about Commander-S since I've been looking for a UI that knows
about the structure of commands' output text.  I haven't gotten it to work,
however.

For one thing, I'm getting these compiler warnings:

Warning: undefined variables
         #{Package 286 jobs}
         handle-signal-default

Warning: undefined variables
         #{Package 291 nuit}
         ignore-signal

Then when I run the commander-s script from the build directory, I get

heap size 5000000 is too small, using 6155008
starting remote handler for condition(exception 10 undefined-global #{Location 
10804 ignore-signal nuit})
Please connect to port 8888
Debug messages will be on /dev/ttyqf

(except my newsreader made me wrap the text -- I put a CR after the space
after "Location")  And if I connect to port 8888, I get

Welcome to the command processor of the remote scsh
#{Exception-continuation (pc 10) (run in nuit)}

followed by a > prompt.  Could these symptoms all reflect an out-of-date
version of a package Commander-S depends on?  My system has

- Mac OS 10.3.7
- scsh 0.6.6 with the two patches from the Commander-S distribution
- Commander-S from CVS, a few days ago
- scsh-install-lib 1.2.0
- scsh-ncurses 1.0
- sunterlib from CVS, about the same day I got Commander-S

There could be other problems... I am still learning about the Scheme48
package system, so the commands I built or ran everything with could be wrong.
Let me know if more details would be helpful.

Thanks,
