The permissions on /doc/procps-1.2.9 as installed from the procps-1.2.9-2 distributed for RH5.2 are -rw-r--r--, but I think they should be -rwxr-xr-x like the rest of the doc files.
sed 's,/doc,/usr/doc,g'
I verified this to be a bug on a 5.2. The permissions are set incorrectly for this directory.
*** Bug 117 has been marked as a duplicate of this bug. *** Missing x permission on /usr/doc/procps* directory
That was caused by a bug in RPM; it will be fixed when we rebuild procps for rawhide.
Corrected status
