How are you setting the pkgsrc compiler to be used?  If you're just
installing the gcc6 package and then pointing CC/CXX to it then yes
you won't get a dependency (pkgsrc can't magically compute that it's
coming from a package and will assume that's a system path), whereas
if you set USE_PKGSRC_GCC=yes and GCC_REQD+=6.0 then you will.
