Both rpm 4.5 and now rpm 5.4 use MD5 as file digest algo.
And ripping out filemd5 index is quite pointless, as the problem is the
inability to install package build with rpm5 on a system with rpm 4.5,
so the real fix is "upgrade to rpm5". But it would be good to know what
is the cause of that bug to not break things before upgrade.
