Again, OSG Client Install Attempt

Yesterday I attempted to install the OSG Client 0.6 on a linux server. I've attempted to install it several times on other machines, but it really wants a RedHat Linux. Which I think is nuts, since I would prefer Solaris or Debian.

It failed after a few minutes saying that this was Rocks 4 and it wants only Rocks 3. I found that irritating.

A friend tells me that I can run it successfully on that machine with

pacman -pretend-platform:RHEL-3 -get OSG:client

This will supposedly work. Whether or not the software will work is another matter, I suppose.

But this morning I tried it on a remote server running Scientific Linux 4, which should be a supported platform. Initially, I sourced setup.sh in bash, because I prefer bash. I got the following error:

Package [/home/USERID/osg:OSG:client] not [installed]:
    Package [/home/USERID/osg:http://vdt.cs.wisc.edu/vdt_161_cache:VDT-Client] not [installed]:
        Package [/home/USERID/osg:http://vdt.cs.wisc.edu/vdt_161_cache:Condor] not [installed]:
            None of the following alternatives succeeded:
                Environment variable [VDTSETUP_CONDOR_LOCATION] has not been set.
                vdt-untar failed to install files from 'condor-6.8.3.x86_rhas_3.tar.gz':
    Failed to unzip 'condor-6.8.3.x86_rhas_3.tar.gz': No such file or directory
                Pacman install failed

Which is entirely unhelpful.

Grieg Cowan's probably got the single most useful stuff out there if you're trying to put your sites terabytes onto a grid using dCache.

Technically, it is indeed possible to allocate [information technology] resources as needed and to change this allocation on very short time scales. However, the ability to dynamically align resource allocations with changing business objectives is largely absent. Thus, the principle reason for the slow commercial adoption of P2P and related technologies is that although such technologies enable sharing, they do not help an organization decide how to best allocate the resources it owns.
