[Squirrel-sql-develop] 3.3.0 compile errors

I am compiling the 3.3 source that I obtained from the download page -
squirrel-sql-3.3.0-source.zip  dated 2011-11-21.  I am compiling it in
eclipse.  There are a lot of compile errors.  I found one that I was
able to correct by adding an additional import.  

This was in fw.datasetviewer.cellcomponent module
IDataTypeComponentFactory.java.   Eclipse was complaining that Dialect
Type could not be resolved to a type.  When I added the import
net.sourceforge.squirrel_sql.fw.dialects.DialectType  The error was
resolved.

My understanding was that this source is stable.  Did I get the wrong
source?  Are there updates to the 3.3.0 source that I should retrieve?  

Many thanks,

Betsy
