I downloaded the latest drupal from the cvs using the command below.

When I tried to install the drupal it gave me a blank page when I clicked on "Install drupal in english". I tried everything from re-downloading the code to commeting some lines in the install.inc file but all in vain but finaly I have fixed it. I know it is kinda dirty way of fixing things. I saw this page http://drupal.org/node/298391 while searching for solution. Though I did not apply the patch. I made the change in the includes/install.inc file manually.

In the function "function drupal_detect_database_types()" Replace this portion of the code.
