My post here 
http://forums.codeblocks.org/index.php/topic,10346.0.html  was not answered. So I suppose the topic is the bug.
At start codeblocks watching for pluggins in /usr/lib/codeblocks/plugin directory but they are placed in /usr/lib64/codeblocks/plugin.
I didn't find there is it could be configured. The earlier builds had no such a problem because they were placed in /usr/share/codeblocks directory.
I'm running on x86_64 Slamd64 linux distro. Codeblocks svn version r5489.
Configure flags:
CONFIGURE_FLAGS+="--with-contrib-plugins=all --enable-static \
 --enable-source-formatter --enable-autosave \
 --enable-class-wizard  --enable-code-completion \
 --enable-compiler --enable-debugger --enable-mime-handler \
 --enable-open-files-list --enable-projects-importer \
 --enable-scripted-wizard  --enable-todo --enable-xpmanifest \
 --enable-pch  --prefix=/usr --disable-debug --libdir="/usr/lib64"
Any comments are welcome!
