CentOS - Feb 2013 - Installing SOGo on Centos 5

Hello,

I was following directions at:
http://www.sogo.nu/english/support/faq/article/how-to-install-sogo-and-sope-through-yum-1.html
to install SOGo on CentOS 5.9 and, noticing that among the dependencies 
is memcached and rpmforge includes a much more recent version than EPEL, 
I preferred rpmforge and therefore I set a higher priority for rpmforge 
repo (see below).

[Note: I guess I could have left out epel in the first place, because I 
saw that no package was used from there, yet I thought I should follow 
the directions at the above page, which claim that epel should be 
enabled, just in case.]

So I did:
     # yum --enablerepo=rpmforge,epel,rpmforge-extras,sogo-rhel5 install 
sogo sogo-devel sogo-debuginfo
where I have the following priorities set:

    [base]
    priority=1
    enabled=1

    [updates]
    priority=1
    enabled=1

    [addons]
    priority=1
    enabled=1

    [extras]
    priority=5
    enabled=1

    [centosplus]
    priority=6
    gpgcheck=1
    enabled=0

    [contrib]
    priority=15

    [rpmforge]
    priority = 2
    enabled = 0

    [rpmforge-extras]
    priority = 2
    enabled = 0

    [epel]
    priority=5
    enabled=0

    [sogo-rhel5]
    enabled=0
    priority=3

but I got:
...
perl-AnyEvent-5.340-1.el5.rfx.x86_64 from rpmforge-extras has depsolving 
problems
   --> Missing Dependency: perl(Net::SSLeay) >= 1.33 is needed by

Error: Missing Dependency: perl(Net::SSLeay) >= 1.33 is needed by

However, it seems an RPM is available at rpmforge-extras (and is > 1.33):

# yum --enablerepo=rpmforge,rpmforge-extras,rpmforge-testing info 
perl-Net-SSLeay
...

Why this package isn't being used during dep solving?

Any ideas? Am I doing something wrong?

Please advise.

Thanks,
