It would not surprise me in the least to find out I did something wrong. :-}
I know I did "yum install db4-devel" as part of packages I believed
were prerequisites to installing Postfix.
My recall is that I was missing a /usr/include file when test building
a Postfix and I did a "yum provides" that lead me to the decision to
install db4-devel.
I am not convinced there are two copied of Berkeley DB installed.
Does this look like two Berkeley DB copies? ...
