bingo. This machine was configured (not by me!) with 2GB swap space.
It has 16GB RAM.

this is with make -j6 and hyperthreads disabled.

Jan  5 21:04:31 r5601g kernel: swap_pager: out of swap space
Jan  5 21:04:31 r5601g kernel: swp_pager_getswapspace(7): failed
Jan  5 21:04:40 r5601g kernel: pid 31026 (c++), jid 0, uid 0, was killed: o=
ut=20
of swap space

I'll ask the remote end to reinstall, this time with 16GB swap.

(I'm thinking maybe the defaults are set too small. The setup was
zfs guided install, the "disk" is a WDC PC SN730 SDBQNTY-256G m2 ssd)

so, the perl problem was down to DTRACE (which might or might not be=20
a chip or a perl problem) and the llvm13 issue was down to swap resources.

thanks everyone for the help
