Hi
I'm really off my league, here
I did a strace on my backuppc 3.0.0 on ubuntu 8.04 (and got "Got reply: ok")
$ strace ./BackupPC_serverMesg status 2> temp.txt
But I get nothing like your trace
$ cat temp.txt |grep connect
connect(3, {sa_family=AF_FILE, path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_FILE, path="/var/run/nscd/socket"}, 110) = -1
ENOENT (No such file or directory)
connect(3, {sa_family=AF_FILE, path="/var/lib/backuppc/BackupPC.sock"}, 110)
= 0
I have all this perl stuff :)

You may want to try, if you didn't yet, to install a stable version of
backuppc instead of BackupPC-3.2.0beta1.
Maybe it makes no difference, I guess
Good luck, hope someone who knows openwrt and perl can give you a hand.
