unable to build the C emulator due to missing verilog.h file

Type of issue: bug report

Impact: no functional change

Other information

Currently, when I try to build the C emulator, the Verilator version for the emulator failed to build due to a missing Verilog.h file. I'm guessing this is due to an incorrect bison installation, but bison was installed correctly on the PATH. Here is the build log:

What is the current behavior?
Verilator installation failed mid parse.

What is the expected behavior?
Verilator installs correctly and the C emulator is built correctly.
