Be aware that on several versions of RPM, the tar file has been created using incorrect permissions. As soon as you install RPM, check your permissions of various directories (/bin, /usr, etc). If the permissions are of 700 (drwx------), then you have been infected by the bug.
To fix these permissions problems, run this shell script:
#!/bin/sh chmod 755 /bin chmod 755 /usr chmod 755 /usr/bin chmod 755 /usr/doc chmod 755 /usr/lib chmod 755 /usr/man chmod 755 /usr/man/man8 chmod 755 /usr/share chmod 755 /usr/share/locale chmod 755 /usr/share/locale/de chmod 755 /usr/share/locale/de/LC_MESSAGES chmod 755 /usr/share/locale/pt-br chmod 755 /usr/share/locale/pt-br/LC_MESSAGES chmod 755 /usr/share/locale/sv chmod 755 /usr/share/locale/sv/LC_MESSAGES chmod 755 /usr/src
