I am setting up Amanda on a Gentoo box with an Overland LoaderXPress and can't seem to get past an amcheck issue. The amdump operation works fine

but amcheck gives this error:

amdump is working but amcheck is not?
I'd first check permissions on amcheck.
It should be root owned and setuid'ed.

dev64 daily # ls -la /usr/sbin/amcheck
-rws--x--- 1 root amanda 40640 Jun 23 00:08 /usr/sbin/amcheck

Here is my amanda.conf:
-----------
org "daily"

mailto "<removed>" # space separated list of operators at your site

dumpuser "amanda"       # the user to run dumps under

is amanda user or amanda's group allowed to read the tape device?

see above

#
inparallel 4            # maximum dumpers that will run in parallel

netusage 1000 # maximum net bandwidth for Amanda, in KB per sec

# a filesystem is due for a full backup once every <dumpcycle> days

"at least" once every dumpcycle

dumpcycle 7 days        # the number of days in the normal dump cycle

where is runspercycle?, i.e. the number of times in 7 days
you will run amdump.

tapecycle 8 tapes       # the number of tapes in rotation

Assuming runspercycle is 7, not a lot of safety in 1 tape more
than a dumpcycle.

bumpsize 20 MB # minimum savings (threshold) to bump level 1 -> 2

bumpdays     1          # minimum days at each level
bumpmult     4          # threshold = bumpsize * (level-1)**bumpmult

# this is a symbol link to "/dev/nsto"

Is this correct, or is it really nst"0" (zero not ohh)?

It is zero, I added that comment to the email for clarity.

tapedev "/dev/tape"     # Linux @ tuck, important: norewinding

Typically I see this link as "ntape" -> nst0 and "tape" -> st0.
Make sure you are pointing to the correct device.

tpchanger "chg-zd-mtx"   # the tape changer script

# this is a symbol link to "/dev/sg0"
changerdev "/dev/changer"    # the tape changer device
changerfile "/etc/amanda/daily/changer" # the tape change status
