Hola Pamela!
First of all, in order to get the mail reaching the people of the mailing list, try to subscribe in here:
http://groups.google.com/group/dbxtalk
I'll check if we can allow posts without subscription, but that is googlegroups stuff :).
On your error, let me check in a while if I can reproduce it. Some things of help to me:
- which pharo version are you using?
- where did you load the image?
- are you using moose?
- how did you load the package?
We are all learning new stuff every day, so do not hesitate to ask :)
