Installation Issue of PostgresPlus-9.0

Dear all,

I am trying to install postgresplus on a Ubuntu10.4 based system.
I  got a problem after installation when i issued the below command :

root@S10-MySQL:/opt/PostgresPlus/9.0SS# bin/psql -Upostgres
Password for user postgres:
psql (9.0.2)
Type "help" for help.

Cannot read termcap database;
using dumb terminal settings.
Aborted
root@S10-MySQL:/opt/PostgresPlus/9.0SS# ls -ls

I followed the same steps as in PostgrePlus-8.4 but don't know how it
occurs.
Please help me to find the reason.
My startup.log says :

2011-02-02 09:02:17 GMT LOG:  could not recognize system time zone
2011-02-02 09:02:17 GMT DETAIL:  The PostgreSQL time zone will be set to
"Etc/GMT-5".
2011-02-02 09:02:17 GMT HINT:  You can specify the correct timezone in
postgresql.conf.
