Per IRC, this may be a helpful clue:

$ port deps qt5-qtbase
Full Name: qt5-qtbase @5.6.2_0
Extract Dependencies: xz
Build Dependencies:   pkgconfig, gawk
Library Dependencies: zlib, libpng, jpeg, fontconfig, freetype, dbus, openssl,
                      tiff, libmng, glib2, icu, pcre, libiconv, harfbuzz,
                      qt5-qtbase

qt5-qtbase depends on itself?

Thanks for catching this.
A fix should show up soon.

In f5017c50/macports-ports:

qt5 PG: do no run certain code if building base

Do not check for installed qtbase if qtbase is being installed.
Do not add qtbase as as dependency if qtbase is being installed.
Fixes #53240
