[Neo] Missing packages: org.neo4j.util.matching.* errors

[francis adediran]

Hi guys,
 i'm having a problem with this source file
UriBasedExecutor.java.

it's giving me errors on these imports in the file
*

import* *org.neo4j.util.matching*.PatternMatch;
*

import* *org.neo4j.util.matching*.PatternMatcher;
*

import* *org.neo4j.util.matching*.PatternNode;

Is this a problem of outdated source file that has not been updated by
someone?

There is no reference to "matching" in the util components trunk

Pls help. i hope to prove Neo4j as de facto graph db for semantic web's
rdf  use if this works?

Thanks

Francis
