can't complete sample job[pscoast] GMT4.5.12

Hello,

I ask a question for the first time. 
I installed GMT4.5.12.(CentOS release 6.4 (Final))
However, test job does not move well. 

It is a sample of an error. 
(It will become an error if pscoast is used. )
> make[1]: Entering directory `/root/app/gmt/gmt-4.5.12/doc/examples'
> cd ex01 ; ./job01.sh
> pscoast: crude resolution shoreline data base not installed
> pscoast: No databases available - aborts
> pscoast: crude resolution shoreline data base not installed

> cd ex04 ; ./job04.sh
> pscoast: low resolution shoreline data base not installed
> pscoast: No databases available - aborts
> cd ex04 ; ./job04c.sh

What has a problem? 
What should I do next? 
Is it insufficient only by performing a [install_gmt4.sh]? 

I got [install_gmt4.sh] by [ftp://ftp.soest.hawaii.edu/gmt4/]
[netcdf] by [ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.gz]

And the used [GMT4param.txt] is here.
