 Hello all,

 I am running CentOS 5.6 64 bit.

 When running "yum -y install ncurses-devel",
 I expect that only ncurses 64 bit version will be installed.

Try: yum -y install ncurses-devel.x86_64

Or, add “exclude=*.i?86” in your /etc/yum.conf before running the same command you did earlier.

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,
