Yesterday I had some problems installing SvnAnt.

When I used the SvnAnt 1.0.0 (bound against subversion 1.3.1) Release I got this error running a svn ant task:

Part of Ant-script:

PLAIN TEXT
XML:
  1. <path id="all-java-libs">
  2.     <fileset dir="${lib.dir}">
  3.         <include name="**/*.jar"/>
  4.     </fileset>
  5. </path>
  6.  
  7. <taskdef resource="org/tigris/subversion/svnant/svnantlib.xml" classpathref="all-java-libs"/>
  8.  
  9. <svn>
  10.     <status path="${basedir}" revisionProperty="revision"/>
  11. </svn>

Error:

144: Problem: failed to create task or type svn
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any declarations have taken place.

After a while I thought trying with a development release SvnAnt 1.2.x (bound against subversion 1.5.0) Release

No error with this release... Strange... Googled for a moment but didn't really find a solution for the stable release.
