I got this error:
ERROR: net-misc/dropbox-39.4.49::net-kit failed (prepare phase): * eapply_user (or default) must be called in src_prepare()! * * Call stack: * ebuild.sh, line 776: Called __ebuild_main 'prepare' * phase-functions.sh, line 1053: Called __dyn_prepare * phase-functions.sh, line 383: Called die * The specific snippet of code: * die "eapply_user (or default) must be called in src_prepare()!" It is xfce4 desktop.

Thanks Cardinal , that worked like charm .
 
Renaming  those files has solved file-collisions problem.
That should be somewhere in the wiki page.
 
Whole package:

thanks to all again

The five files detected in the file collision do not belong to app-eselect/eselect-python-20140125 according to the equery output.
Renaming the files should not break anything.
Rename each file by adding ~ to the name so there is no collision.
 *     /usr/bin/python3
 *     /usr/bin/python2
 *     /usr/bin/python
 *     /usr/bin/pydoc
 *     /usr/bin/2to3
 *     /usr/bin/python-config
 
After you finish renaming try to update @world.
