looks like the same issue as 53619

I fixed it by remaking the link

sudo ln -s /opt/local/libexec/qt4/lib/libqscintilla2_qt4.13.0.0.dylib /opt/local/libexec/qt4/lib/libqscintilla2.dylib

which works fine, but the proper fix is probably to patch openscad to use the new library naming scheme for qscintilla

In 4738dad7/macports-ports:

OpenSCAD: fix build when using libc++, removing minimum OS constraint to allow for Mac OS older than 10.7 when bootstrapping libc++; fix library name of qscintilla for update in 2.10.0 release. Addresses tickets #51840 and #53623 .

Thanks for the pointer!
