Part of it could be but I'm not sure.
The 6.1 VM provided by Fam has /usr/local mounted with wxallowed, I
tried building/running there and nothing changed, mmap() still returns
ENOTSUP:

Since the current script build into /var/tmp (which is symlinked to
/tmp) I also mounted /tmp wxallowed using the following patch:
