error installing on mingw

Hi all-

I tried to install PostgreSQL for mingw. I get the following msg. It won't finish installing the bin directory.

Any idea how I can fix it? It is PostgreSQL 11.2 from source windows trying to install on 64 bit mingw. One person said they just used sudo before make install to get past it. I can't do that. I use mingw32-make instead of just make for mingw.

thanks! roboloki
