>Description:
The codeblocks IDE build failure appears to be a fallout of the renaming of the GTK package to GTK2 to allow for the introduction of GTK3.  During build it reports that it can't find GTK2 and it seems to be looking for "gtk+" rather than "gtk2+" (or "gtk3+").  It may build and work with either GTK2 or GTK3, not sure.
>How-To-Repeat:
Attempt building editors/codeblocks in pkgsrc-2018Q3 or pkgsrc-current.
>Fix:
Unknown, the GTK magic in pkgsrc builds is beyond my meager skill set.
