[OpenIndiana-discuss] What to do about not having a compiler suitable to install VBox

[Harry Putnam]

Attempting to install an VBox pkg from the Oracle site I run into this
output:

pkgadd -d ./*.pkg 

[...]

Oracle VM VirtualBox(i386) 6.1.14,REV=2020.09.04.10.03.140239

I do have developer gcc-7 and gcc-7-runtime, but apparently that is
too new .. hehe.
