The files and directories in the Subversion distribution tarball lack
read/execute permissions for "other" entities (i.e. the last digit of the octal
triplet is 0), and two files in ac-helpers/ have a bogus mode of 754.
The following commands, invoked in the top-level directory of the tarball tree,
fix the problem:
find . -perm 640 -exec chmod 644 {} \;
find . -perm 750 -exec chmod 755 {} \;
chmod 755 ac-helpers/config.{guess,sub}
I am building Subversion on various systems off a read-only NFS mount, so this
is something I currently have to do for every new release.
