Paul is right. I've played with the compiler tool a bit and it brings "download and install" approach directly, you don't have to do something except what's written in a couple of lines in readme. You did what wasn't required - and you've got what wasn't supposed, it's quite logical.
Ok.. I screwed up.. What I did was follow the installation instructions of BOTH the readme
AND also the manual
. When I should have only
followed the readme.
Usually following the steps in the manual is a good thing.
I don't recall anything telling me not to follow the manual if I used the compiler.
So though I see your point, I don't consider what I did to have been a dense move.
But anyway all is well now, and I'm thankful for a great program.
