Because of Hans (thanks Hans) suggestion I did a NO SVN pkgbild.
It should be the REAL latest version of pd-extended 0.43-x
here:
https://aur.archlinux.org/packages.php?ID=44798

it was born from:
https://pure-data.svn.sourceforge.net/svnroot/pure-data/branches/pd-extended/0.43  ------- the latest pd-extended 0.43.x
git://pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem                                                    ------- the latest GEM
git://pure-data.git.sourceforge.net/gitroot/pure-data/pd-extended.git                            ------- the latest pd-extended core
+ mime types (it depends now on hicolor-icon-theme)

or am I wrong about the latest sources ??

I have a question again.  On aur.archlinux.org it is shown as Pure Data Extended 0.43-1 version, BUT IT IS 0.43-4 NOW. Where I did mistake in PKGBUILD ?
cheers
