According to that output, perl was already using 464MB, and a malloc
request for 64MB failed, which is reasonable since the default hard
datasize limit on FreeBSD is 512MB.  To raise it, put this in
/boot/loader.conf and reboot:

kern.maxdsiz="1024M"

Also running perl 5.8.6, on the same mailbox?  Maybe different perl
versions allocate memory differently.
