Hi, I just tried to install R-1.9.1 on a machine running Mac OSX 10.2.8. I am the only user of the machine. The install appears to go most of the way, then fail late. Looking at the messages written to the console, it appears that the installation process does not have permission to do various things (such as write to the disk!) Normally when I install from a pre-built package, after hitting the Install button there is a drop down box requiring that I supply the root password. This didn't happen with the R install, making me wonder if the person who built the install package set it up properly (perhaps there was an assumption that the machine would be a multi-user machine and that software would only be installed by the administrator?). In any case, I would like to bring this to the attention of the OS X builder/maintainer and see if anyone has a suggestion that doesn't require me to spend a lot of time. Thanks, Allan Dobbins
