Hi There,

I have a VPS machine on Slicehost. The machine is running Ubuntu 7.10 64-bit edition. I have followed this tutorial http://www.zimbra.com/forums/install...t-install.html for installing zimbra on 64-bit machines, and it all seems fine until the last part of installing packages (i assume) were i get:

### OUTPUT BEGINS ###
Installing packages
zimbra-core......zimbra-core_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-ldap......zimbra-ldap_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-logger......zimbra-logger_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-mta......zimbra-mta_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-snmp......zimbra-snmp_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-store......zimbra-store_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-apache......zimbra-apache_5.0.2_GA_1975.UBUNTU6_i386.deb...done zimbra-spell......zimbra-spell_5.0.2_GA_1975.UBUNTU6_i386.deb...done

/usr/bin/perl: symbol lookup error: /opt/zimbra/zimbramon/lib/i486-linux-gnu-thread-multi/auto/IO/IO.so: undefined symbol: Perl_Tstack_sp_ptr

### OUTPUT ENDS ###

I checked your forum, and i read that this problem could be due to DNS configuration problems. However, i think that my DNS is working fine. I have set up DNS records through an online utility that the hosting company provides.

I checked the following tutorial on installing Zimbra on Ubuntu, http://wiki.zimbra.com/index.php?tit..._Install_Guide , and it seems that my DNS is set up nicely. I can ping outside servers (google.com) and when i do an nslookup on my domain name, i get back the following:

### OUTPUT BEGINS ###

Server: 67.207.128.5 (which is some IP address at Slicehost)
Address: 67.207.128.5#53

Non-authoritative answer:
Name: mydomain.net

### OUTPUT ENDS ###
Address: the ip address that i get when i ping/nslookup my domain from home
[/CODE]

I am not 100% sure, but it seems that DNS is working fine (right?) so, what could be going wrong ?

Any help here please ?

Thanks,
