ABL Unit on Centos - Failure to invoke ABLUnit runtime

Hi ABLUnit Guru's

I need your help. I'm running OE115 (64bit) on centos (64bit). I've copied ablunit.pl from a OE115 windows (PSODE) envirnment 
and used PCT-194 and used relevant ant-ablunit.jar.

I cant seem to get ABLUnit running tests for me. Below is my Ant build.xml file

------------------------------------------------------------------------------------------------
<target name="ablunit-taskdef">
<taskdef name="ablunit"
classname="com.progress.openedge.ant.ablunit.ABLUnitTask"
classpath="/usr/ant/apache-ant-115/lib/ant-ablunit.jar" />
</target>

<target name="unit-test-application" depends="ablunit-taskdef">
<!-- This peice runs the unit test suite -->
<echo>Apply procedure, function and class unit tests to application ...</echo>

<ablunit dlc="/psc/115/dlc" environment="tty"
printsummary="true" haltonerror="no" haltonfailure="no" tempdir="${base.dir}/${build.area.dir}">
<dbinfo name="/mnt/xvdp/fw-ut/beta/${test.area.dir}/${db.name}.db" />
<propath>
<pathelement location="${base.dir}/${build.area.dir}/UnitTests" />
<pathelement location="${base.dir}/${test.area.dir}/fw-${release}.pl" />
<pathelement location="/psc/115/dlc/tty/ablunit.pl" />
<pathelement location="/psc/115/dlc/tty/OpenEdge.Core.pl" />
</propath>
<test name="${base.dir}/${build.area.dir}/UnitTests/Frameworks/Enumerations/utAttributeOwnerEnum.cls"
format="xml" />
</ablunit>
</target>

------------------------------------------------------------------------------------------------

Output from the Ant task is: 

ablunit-taskdef:

unit-test-application:
[echo] Apply procedure, function and class unit tests to application ...
[ablunit] Running /frameworks/fw-ut/beta/tmp/UnitTests/Frameworks/Enumerations/utAttributeOwnerEnum.cls
