Getting an error while running rake command on a rails 2 project with postgres and postgis

Hi All,

I am runnning a rails 2 project with the following gems, georuby,
spatial_adapter. And Postgres db as backend. But I am facing this error.
I tired installing postgis also but still get this. Any ideas what i
should try. This is a rails 2.3 project ,so is it some version
requirements i am missing. The statement seems to be correct and i tied
looking it up too. Please help.
