description:
include sys/param.h for MIN/MAX, needed when building in pkgsrc
tolerate set version failing in another location too.

this now works well enough for mesa 18.2.0 to display glxgears followed
soon by X crashing and refusing to start again until the machine is
rebooted, at least in my case.
