Installation fails in Linux

Hi there,
I have just intstalled the app manager 6.0 in ly redhat linux 9.0 and there is an
error in the unpackout.txt saying
Error: Could not open input file: /home/jeyakumaran/AdventNet/ME/AppManager6/working/classes/JimiProClasses.pack.gz
Error: Could not open input file: /home/jeyakumaran/AdventNet/ME/AppManager6/working/apache/tomcat/common/lib/ant.pack.gz

What could be the reson.

Thanks in advance ,
