(The first time I tried, without using "sudo su -“, I had copied the “echo rsync” command directly from the https://www.openmodelica.org/download/download-mac <https://www.openmodelica.org/download/download-mac> instructions. But the second time, using "sudo su -“ I just typed the command, clearly a mistake.

I know that a long time back, the default set of compilers didn’t work with OpenModelica, but that for a few years at least, the default set of variants has worked fine for building and using it.  Those instructions have probably just not been updated in a long time.  

I don’t know about the link issue, but I haven’t yet seen any problem caused by it….so far (in years of use)
