Thank you Scott and Dave. Dave , the url given , not really helpful unless I go through each and every details,I dont know -searcg the page for the word segmentation returns nothing . another thing ,just to let you know my postGIS installation through StackBuilder still failed by returning error after clicking Next button to start installation after successfully downloaded. It says 1 skip installation because of error , sort of.
Scott , my latest attempt to install in centos 5 this time work well by re-downloading .bin installer . But , in fc10 the ./postgresql-8.3.5-1-linux.bin command still to no avail. for now , the text mode , ./postgresql-8.3.5-1-linux.bin --mode text is the only way to go in fc10. Thanks.
