Questions about running Arla on Solaris 7

[Jeff Plum]

Arla was configured on a Solaris 7 workstation.  The command arlad
-t worked, but the module xfs would not load.
Here were the steps taken:
Kerberos version krb4-0.9.9 was installed.  The version of kerberos
installed uses afsys.c version 1.57 not version 1.59 or higher as noted
in the INSTALL directions.  Kerberos with the afsys.c version 1.59
or higher was not located.
Arla was installed.
arlad -t ran and allowed access to an AFS cell.
Added xfs 140 to /etc/name_to_major
Added xfs 102 to /etc/name_to_sysnum (Solaris 7 uses 105)
Rebooted workstation
Modloaded xfs
#modload xfs
can't load module:  No such file or directory.
What did I miss?
Thanks
