Any idea what is going on here?

@oharboe 
Have you removed `OpenROAD-flow-scripts/tools` directory before building again.
Sometimes it may cause the issue.
@vvbandeira Can please check this?

### maliberty
which binary is it building when the error happens?

### oharboe
Rejoice! I finally got it to compile. I deleted the *entire* ORFS folder, recloned, reran sudo ./setup.sh and then the build worked.

So, somewhere inside the ORFS folder there was an out of date file that wasn't being built...

It would be nice to know what exactly is going wrong, but I guess that will have to wait until next time it breaks and I do some more investigations?
