installing bzr on CentOS 5

[Keith Bierman]

I'd found the old post: http://article.gmane.org/gmane.comp.version-
control.bazaar-ng.general/36410/match=centos+5

However, that wasn't working. But I did find rpmforge's repos do have 
bzr and bzrtools (but not -gtk and olive).

after installation of bzr itself, I sought to install bzr-explorer and 
since that wasn't in the repos (EPEL or sourceforge) I tried

mkdir -p .bazaar/plugins
cd .bazaar/plugins
 
bzr branch lp:qbzr  
bzr branch lp:bzr-explorer explorer


Sadly then explorer fails rather badly (see below for details).   Is 
there a good way to install bzr with the GUI tools on CentOS 5 these 
days? If so, can someone please point me to the appropriate RTFM? Thanks 
in advance!
