I am not absolutely sure, but here's what happened:

1. I had a previous version of GEM installed. (0.5)

2. I then installed the latest version of GEM (0.8) and tried to run the 
unit tests. Unit tests failed.

3. I did a gem list - of the entries the one for wet was - wet-web (0.5, 
0.8). In the ${ruby_gem} directory, there were two wet-web directories

4. Since these tests _could not_ have passed in 0.5, I thought that the 
problem was due to the two gem files trying to co-exist.

5. I did a gem uninstall wet-web -a.

6. I then installed 0.8 gem again and ran the unit tests. This time, the 
tests passed.

My guess is that the problem happened due to the fact that there were 
both the gems installed on the system and the tests were trying to 
access the wrong version. (However I didn't do a good tester's job by 
trying to reproduce the problem. I was simply happy that everything 
worked for me and forgot about it)
