I recently tried to install wine from src and ran into a problem. when it prompted me to enter the root password to do a "make install" I did so, and it proceeded to tell me that I entered an incorrect password. I tried this several times realizing it is possible to enter the password incorrectly, but each time gave the same result. Now I know the password was correct as I am the only user of this box and I installed Slackware 9.0 myself.
As a request of your install app, I am e-mailing you this.
Thanks Bill
