Problem Building Trunk

I'm having trouble building some of the targets such as clean.db.schema and 
build.bin.dist.  It looks like its related to the setup of the HSQLDB 
tables.  I can build things like build.war just fine.

The clean.db.schema error seems to be related to how build-db.xml is set 
up.  I first tried adding 'expandproperties="true"' to the <sql.tool> 
definition, but this did not help.

The error in build.bin.dist fails on the dependent target 'apply.patch'. 
It looks like one or more of the patch files is not relevant.

Ant output is below.  Any ideas?  Using JDK 1.5.0._16, Ant 1.7.
