[Sazuma Trading]

Can Anybody help me??? I am quite a beginner on LINUX
and I found RT and think its great.. 

but now i am trying to install it and it seems that
I am having problems with MYSQL:

mkdir -p /usr/local/rt/lib
cp -rp ./lib/* /usr/local/rt/lib
/usr/bin/mysqladmin -h localhost -u root -pxxxxxxx create rt
/usr/bin/mysqladmin: create of 'rt' failed
error: 'Can't create database 'rt'. (errno: 28)'
make: [database] Error 1 (ignored)
/usr/bin/mysql -h localhost -u root -pxxxxxxx rt < etc/schema
ERROR 1049: Unknown database 'rt'
make: *** [database] Error 1

I cant create a database anymore (not even manually!)
