Problems installing on Linux - Mailing list pgsql-novice

Hey all,

I've been using Postgres for a while on Windows, and am trying to set
it up on my Linux co-lo (Redhat 9).

When I try to install it, I get dependency problems that I can't find
an easy answer to. For example, when installing the libs, I get:

[root@u15174543 root]# rpm -il postgresql-libs-8.0.0rc1-2PGDG.i686.rpm
warning: postgresql-libs-8.0.0rc1-2PGDG.i686.rpm: V3 DSA signature:
NOKEY, key ID 748f7d0e
error: Failed dependencies:
        libcom_err.so.3 is needed by postgresql-libs-8.0.0rc1-2PGDG

Now, I know libcom_err.so.3 is part of kerberos; I've got
libcom_err.so.2 installed, apparently as part of the krb5-libs-1.3.4-6
package. Oddly enough, when I google libcom_err.so.3, I see it as part
of the krb5-libs-1.2.x package. So, do I need to downgrade my kerberos
libraries, or is there a better/easier/won'tscrewanythingelseup way to
get libcom_err.so.3?

Thanks,

Adam
