[Scribus] Debian dependency issue

[Tony King]

I'm new to debian-type systems (SimplyMepis) and I recently upgraded to
1.2.1-1 used the latest deb from the scribus repository.  After the
upgrade came the error message 

"The following packages have unmet dependencies:
  scribus: Depends: libcupsys2-gnutls10 (>= 1.1.23-1) but 1.1.20final
+rc1-5 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or
specify a solution).
RESULT=100"

On running 'apt-get -f install' I still can't get the missing dependency

viz:
"Get:1 ftp://ftp.us.debian.org testing/main libcupsys2-gnutls10 1.1.23-3
[74.2kB]
Err ftp://ftp.us.debian.org testing/main libcupsys2-gnutls10 1.1.23-3

E: Unable to fetch some archives, maybe run apt-get update or try with
--fix-missing?"

My apt-sources are

ftp://ftp.us.debian.org/debian testing main contrib non-free
ftp://ftp.us.debian.org/debian unstable main contrib non-free
ftp://non-us.debian.org/debian-non-US testing/non-US main contrib
ftp://non-us.debian.org/debian-non-US unstable/non-US main contrib 
http://download.videolan.org/pub/videolan/debian sid main
http://2004.mepis.org/mepis testing main
ftp://ftp.nerim.net/debian-marillat/ unstable main
http://www.scribus.org.uk/downloads/deb binary/

Can anyone suggest a source where I might obtain the missing dep?  I
don't want to compile from source, unless I have to.  Doing that wreaked
havoc on my previous Fedora system.

TIA
