!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

sys-libs/readline:0

  ('ebuild', '/', 'sys-libs/readline-6.0_p3', 'merge') pulled in by
      >=sys-libs/readline-5.1 required by ('installed', '/', 'net-ftp/lftp-3.7.14', 'nomerge')
          sys-libs/readline required by ('installed', '/', 'dev-lang/php-5.2.10', 'nomerge')

              (and 15 more)


    It may be possible to solve this problem by using package.mask to
    prevent one of those packages from being selected. However, it is also
    possible that conflicting dependencies exist such that they are
    impossible to satisfy simultaneously. If such a conflict exists in the
    dependencies of two different packages, then those packages can not be
    installed simultaneously.
