Question about RPM?

[Dan Swartzendruber]

I'm running a 5.3 headless server.  I had been using amanda for tape 
backup, but decided to try out arkeia.  Unfortunately, they don't seem to 
support FreeBSD, so I thought I'd try it under linux emulation.  I 
installed the linux_based-rh-9 port, and that seemed to go fine.  I 
confirmed that the requisite KLDs were loaded.  Unfortunately, if I try to 
install the arkeia RPM (with the usual 'rpm -ivh arkeiaXXXX.rpm' 
incantation), it gives me a raft of warnings about various shared libraries 
being needed, as well as /bin/sh.  I don't recall seeing any errors during 
either the build or the install of the base package, so I'm mystified as to 
why the installation of that rpm failed.  Any thoughts?
