This is not a blocker.

Read the warning, it says an update or rebuild was skipped due to a 
dependency conflict. In your casejasper-1.900.1-r9 was not done due to 
gdk-pixbuf requirements. Presumably, what you already have keeps pixbuf 
happy

Blockers in that output usually have "!!" annotations at the beginning.

portage is doing what's expected. You don't have -a in the command line 
and there's nothing stopping portage from moving forward with the build.

SO it moved forward with the build.
