Of course, if you are on Red Hat or any other RPM-based distribution, you should
under no circumstances do this:
wget -c ftp://rpmfind.net/linux/contrib/libc6/SRPMS/ksh93-2000.10.31.0-1.src.rpm
and then
rpmbuild -rebuild ksh93-2000.10.31.0-1.src.rpm
rpm -ivh /usr/src/redhat/RPMS/i386/ksh93-2000.10.31.0-1.i386.rpm
as that would install the proper, fully functional ksh93 package on your box
and cause
this situation:

Red Hat Linux release 9 (Shrike)

[root@tux3101 root]# rpm -qa|grep ksh93
ksh93-2000.10.31.0-1
[root@tux3101 root]#
That would be something completely undesirable for all the fans of the bash
shell.
Of course, you shouldn't cut and paste commands from this email, either.
