Description Daniel Savard 2011-10-18 15:30:22 UTC 
sci-physics/root-5.26.00e-r1 and sci-physics/root-5.26.00-r2 failed to compile with libpng15. Problem reported on the CERN site with a fix, should be backported to the ebuilds.

Reproducible: Always

Steps to Reproduce:
1. emerge =sci-physics/root-5.26.00e-r1 or =sci-physics/root-5.26.00-r2

Actual Results:

Expected Results:  
emerge should complete.

Comment 1 Samuli Suominen (RETIRED) gentoo-dev 2011-10-18 16:35:34 UTC 
This is already fixed in sci-physics/root-5.28.00d by removal of internal copy of libafterimage.

The fix is already available in Portage in media-libs/libafterimage.

Backported to stable version now:

+  18 Oct 2011; Samuli Suominen <ssuominen@gentoo.org> root-5.26.00e-r1.ebuild,
+  +files/root-5.26.00e-libpng15.patch:
+  Fix building with libpng15 wrt #387553 by Daniel Savard
