I have no particular insight, but I think you are installing in a
difficult way. Here are the best ways to install WL (in my opinion) on
Ubuntu, in descending order of preference:

1. Use el-get with semi-epg. [1]
2. Use el-get with semi.
3. Use the wl-beta Ubuntu/Debian package.
4. Use the Makefile distributed with wl to build. (The Makefile makes
choices of what to install based on the version of emacs you are
using. It is inviting trouble to not use it.)

I wrote this wiki article, but it’s not about the “pgg is obsolete
message”. The pgg* files do not seem to be included in the default git
branch of the semi distributed on github, so I guess that advice is
out of date.

1. Here is my el-get recipe for wanderlust with semi-epg:

(setq el-get-sources
      '((:name semi-epg
         :description "SEMI is a library to provide MIME feature for GNU Emacs."
         :depends flim
         :type github
         :branch "semi-1_14-wl"
         :pkgname "ikazuhiro/semi-epg"
         :build
         (mapcar
          (lambda (target)
            (list el-get-emacs
                  (mapcar (lambda (pkg)
                            (mapcar (lambda (d) `("-L" ,d)) (el-get-load-path pkg)))
                          '("apel" "flim"))
                  
                  (split-string "-batch -q -no-site-file -l SEMI-MK -f")
                  target
                  "prefix" "site-lisp" "site-lisp"))
          '("compile-semi" "install-semi"))
         :load-path ("site-lisp/semi/"))
      (:name wanderlust
       :description "Wanderlust bootstrap."
       :depends semi-epg
       :type github
       :pkgname "wanderlust/wanderlust"
       :build (mapcar
               (lambda (target-and-dirs)
                 (list el-get-emacs
                       (mapcar (lambda (pkg)
                                 (mapcar (lambda (d) `("-L" ,d)) (el-get-load-path pkg)))
                               (append
                                '("apel" "flim" "semi")
                                (when (el-get-package-exists-p "bbdb") (list "bbdb"))))
                       "--eval" (el-get-print-to-string
                                 '(progn (setq wl-install-utils t)
                                         (setq wl-info-lang "en")
                                         (setq wl-news-lang "en")))

                       (split-string "-batch -q -no-site-file -l WL-MK -f")
                       target-and-dirs))
               '(("wl-texinfo-format" "doc")
                 ("compile-wl-package"  "site-lisp" "icons")
                 ("install-wl-package" "site-lisp" "icons")))
       :info "doc/wl.info"
       :load-path ("site-lisp/wl" "utils"))))
