I was looking forward to putting the FC4 version into action, but had this problem after running install:
zimbra-spell-3.0.0_M2_746.FC4-20051116155303.i386.rpm installation failed
It was installing fine up to that point
I used mikeygstl's Fedora Core 4 how-to, but had to yum libstdc++.so.5
It's FC 4 on a Pentium 1.5, 512 megs.
I told it to try again, but it is writing a config file.
