For some reason the export command isn't found (I'm using whatever shell su gives me for root) 
but digging through the make log found an old error that's been around for some time:

In file included from /usr/ports/www/webkit2-gtk3/work/webkitgtk-2.20.5/Source/JavaScriptCore/l
lint/LowLevelInterpreter.cpp:559:
DerivedSources/JavaScriptCore/LLIntAssembly.h:795:2: error: Missing globaladdr implementation
#error Missing globaladdr implementation

If somebody is aware of a fix please clue me in.

Thanks for reading,
