Created attachment 204268 [details] patch GCC doesn't include sys/types.h by default, which is needed for uint. Error: https://talos.anongoth.pl/data/powerpc64-default/2019-05-05_01h04m26s/logs/errors/yoshimi-1.5.10.2.log Include it in src/Misc/RandomGen.h to fix build.
Let's wait until upstream says ok.
This should work out-of-the-box now after the update to 1.5.11 in ports r501364.
