p.s. Please tell me that you've installed BOTH open-source and binary packages. ok...I installed both packages...but I'm lying :-) Probably need a message in makemkv like "install the binary package as well, you idiot!" when it can't find makemkvcon or any binaries it links to instead of ...

Anyone ever see this or know of any way to get a more useful error msg?

Compile/install had no errors, but when I run makemkv, it puts up this error msg in a dialog box
