Thanks for all suggestions! I had an old git tree in the build dir which prevented a build.
Though, I managed a successful build without reading any of your comments (and not knowing why it failed before) 'cause every reply went into my 'Sent Mail' folder not showing up in 'Inbox' - never had it before :( Only found your replies when already updated AUR Is it save to update/change the version scheme on AUR without going with epoch? rtf
