emerge of the newer matplotlib fails also because of sandbox violations (other reason being #455968). my currently installed sandbox is 2.5 (latest stable) during the compile phase of emerge I can see 2 windows being opened in my X environment: one is eog and the other one is from imagemagick's display. Reproducible: Always

Created attachment 338196 [details] build log (bzipped) also these are my use flags for matplotlib. cairo doc examples excel gtk gtk3 latex qt4 wxwidgets -fltk -test -tk
Hmm, looks like 'unset DISPLAY' is not respected.
I've just committed a supposed fix. When it gets to you (probably a few hours for rsync to catch up), please test if it works.
