I had the patch problem but I manually created that file and
solr nightly builds fine.
After replacing solr.war with apache-solr-solrj-1.3-dev.jar,
in solrconfig.xml, I added this:
<searchComponent name="collapse"
class="org.apache.solr.handler.component.CollapseComponent" />
Then added this to the standard and dismax handler handler
<requestHandler name="standard" ...
<arr name="components">
<str>collapse</str>
</arr>
</requestHandler>
I added &collapse.field=<field>&collapse.threshold=<n>, and the result
collapsed as expected.
