There seems to be a yum dependency problem between rpm packages 
openssl-0.9.7a-43.17 and (newer?) openssl-0.9.7a-43.17.el4_6.1 in the SL 
4.6 yum repositories.

The first package was installed from the SL 4.5 yum repo, but the latter 
with the ".el4_6.1" ending seems to be the new naming scheme for the SL 
4.6 yum repo.

I manually updated the yum sl-base repo from 4.5 to 4.6. The ran "yum 
clean all" and "yum update" before trying to install openssl-devel.

I think I will install openssl-devel from the SL 4.5 distro, and then 
try to yum update them to the "el4_6" rpm packages.

We have SL4.6 x86_64 with openssl installed:
[root@gryphon ~]# yum list openssl-devel openssl-*

We tried to install openssl-devel rpm package via yum:
[root@gryphon ~]# yum install openssl-devel

PS We encountered similar problems trying to install openldap-devel package.
