Created attachment 402720 [details] config.log Ebuild missing TeX depends with doc USE flag enabled: configure:16535: error: Documentation enabled but pdftex was not found in your path
Jeroen, You've been maintaining this package for a while now.
All libvdpau ebuilds have USE=doc depend on virtual/latex-base, and virtual/latex-base depends on dev-texlive/texlive-latexrecommended which depends on app-text/texlive-core.
