Has anyone installed yt-dev from scratch recently and used the newer than 0.8.7 Forthon(s)? I was able to use make to compile the 8.8 and 8.9 after removing the --with-numpy argument from the Makefile inside the yt/utilities/kdtree, however, I get fKD' is not defined when I use functions that requires the kd-tree. I was able to bypass this problem by reinstalling YT and then using Forthon 0.8.7 (removing Forthon 8.8/8.9 then installing 8.7 then reinstallling YT did not work). I was wondering if anyone else ran into the same issue? Not urgent because 8.7 works. From G.S.
