[scribus] Cmake problem

[Roger]

Downloaded scribus 1.3.5 svn, run Cmake
error me4ssage is:
Qt4 Found OK
-- Building without Qt3 Support (GOOD)

CMake Error at /usr/share/cmake/Modules/FindCups.cmake:42 (MESSAGE):

   CMakeLists.txt:564 (FIND_PACKAGE)

I run Fedora 11 x96_64
I have gimp and just downloaded gimp libs
  whereis gimp
gimp: /usr/bin/gimp /etc/gimp /usr/lib64/gimp /usr/share/gimp 
/usr/share/man/man1/gimp.1.gz

Does scribus require i386_32 bit files or will it compile on 64 bit.
Are there any traps for young players that I have missed.
TIA
Roger
