Hey Brian,

This is not error, just a warning. This note means that this
class/library is not used because it is duplicated in another library
and I'm nearly sure it does not lead to any troubles, instability or
dysfunction. In coming new release we will take it into account to avoid
even such warnings to not appear.

I suppose you are trying to run two services running on the same port,
isn't it? Please try to check if 8180 port is available before starting
tomcat
netstat -lnp | grep 8180
(it is recommended to run command above as superuser; as regular user
you can not have enough privileges)
and check which other perfsonar services are already installed
rpm -qa |grep perfsonar

Otherwise it would be very helpful to send all the messages which fit
into '....'.

Best regards,
Wiktor
