Hi,

the installer for linuxmusl-64 creates invalid directory for binary files. There may be a bug in the file mtx-install.lua:

    --
    ["linux-64"]       = "linux-64",
    ["linux64"]        = "linux-64",
    --
-    ["linuxmusl-64"]   = "linuxmusl",
+   ["linuxmusl-64"]   = "linuxmusl-64",
    ["linuxmusl"]      = "linuxmusl",
    --
    ["linux-armhf"]    = "linux-armhf",

Best regards
Martin Hasoň
