Newbie alert.

Using a fresh 3.10.2 image (Squeak3.10.2-7179-basic) and instructions 
from here:

http://wiki.squeak.org/squeak/5897

Workspace:

(HTTPSocket httpGet: 'installer.pbwiki.com/f/Installer.st') fileIn.

...after "Reading Stream" results in a Transcript of:

(user is Undeclared)  (password is Undeclared)  (user is Undeclared) 
(password is Undeclared)
Installer (Bindings is Undeclared)  (ReleaseBuilderFor3dot10 is 
Undeclared)  (ReleaseBuilderFor3dot10 is Undeclared) 
(ReleaseBuilderFor3dot10 is Undeclared)  (MCCsReader is Undeclared) 
(user is Undeclared)  (user is Undeclared)

Next I tried downloading Installer.st by hand and just doing a fileIn with:

(FileStream readOnlyFileNamed: 'Installer.st') fileIn.

...and that wins me about the same failure, more or less.  Can someone 
clue me in how to get this in a fresh image (or else point me towards a 
better starting point).  Thanks!
