I don't know the solution to your current predicament but let me explain the install error.
> The following files are already installed on the system and are being > used by another package: > /var/svc/manifest/application/graphical-login <attribute change only> The SUNWgnome-display-mgr-root/pkgmap file lists the files to be installed and the owner/group/attributes for each file. If pkgadd finds a file already installed it will compare the files owner/group/attr with that listed in the pkgmap file. If they differ then you get the 'attribute change only' error. Such a difference often indicates that the file has been edited, or that a package has been installed from source (via a 'configure; make; make install' process).
