This is what I did and observed.

1. Add "exclude = *.i?86" to /etc/yum.conf
    cf. 
http://wiki.centos.org/FAQ/General#head-357346ff0bf7c14b0849c3bcce39677aaca528e9

2. Query
     yum search ncurses-devel
    Query result: Two ncurses-devel are *still* there!

3. Try to uninstall
      rpm -e `rpm -q --queryformat "%{name}.%{arch}\n" ncurses-devel`
      It works like charm,  "rpm -qa | grep ncurses-devel"

4. Reinstall
     sudo yum -y install ncurses-devel
     Well, this time only 64 bit one was installed.
    -> ncurses-devel-5.5-24.20060715.x86_64.rpm

# 5. Other "duplicated" rpms
#    rpm -qa --queryformat='%{n}-%{v}-%{r}.%{arch}\n' | grep 
'\.i[3456]86$' | sort

Thank you,
