GNUTAR not found on my system


Dear amanda wizards;

I've just installed the amanda client on a Solaris 9 machine,
and tried to set up the backup of the partitions. However,
that just doesn't happen. The server writes in the report:

FAILURE AND STRANGE DUMP SUMMARY:
  tony       /tmp lev 0 FAILED [missing result for /tmp in tony response]
  tony       /var lev 0 FAILED [missing result for /var in tony response]
  tony       /usr lev 0 FAILED [missing result for /usr in tony response]
  tony       / lev 0 FAILED [missing result for / in tony response]


That's for the four mounts I'm trying to tar.

OK. So I go to the debug messages on client, in /tmp/amanda and here's
what I see:

amandad: time 0.006: bsd security: remote host backup1.coloc.net user operator 
local user amanda
amandad: time 0.006: amandahosts security check passed
amandad: time 0.006: running service "/usr/local/amanda/libexec/sendsize"
calcsize: gnutar not available on this system
calcsize: gnutar not available on this system
calcsize: gnutar not available on this system
calcsize: gnutar not available on this system


I tried to look this up in the provided documentation & forums,
but found nothing. What could be causing the problem?

Here's my configuration:

Thank you so much for your time.

Hope to hear from you soon.
