@User: The MiM cap error was caused by copy & paste issues when creating the MiM2 cap section from the MiM cap section---some references were still to the lower MiM cap and cause the errors you see. I just fixed and pushed the tech file in open_pdks (pushed to the master branch on opencircuitdesign.com). Quick note: If you want to install the tech file from open_pdks without building and installing the rest of the PDK, cd to the sky130/ directory and type "make tools-a" then "make install". That will build only the EDA tool setups, not the libraries.
