I was updating Fedora 14 and got the error Transaction Check Error: file /usr/include/db4.7.25/db.h from install of compat-db47-4.7.25-16.fc14.x86_64 conflicts with file from package compat-db-headers-4.7.25-15.fc13.noarch It looks like compat-db-headers has been removed as a separate package but the packaging of compat-db47 doesn't tell yum what to do if compat-db-headers is installed.
