erk. don't suppose it's possible to track down which compilation uses
so much ram and see if a lower optimisation level for that file would
help?

port builds are normally done with class 'pbuild' which on amd64 has
default ":datasize-cur=12G:" ...

same comment as before about version numbering

normally put a blank line before the license comment (and just one
blank line not two after)

don't add the python dep like this, add lang/python to MODULES instead

split onto lines i.e.

CONFIGURE_ARGS=	-DARCH="generic;himbaechel" \
		-DHIMBAECHEL_UARCH="gatemate" \
		...

do you really need the version number in the prjpeppercorn dir?
apart from being a pain because you'll need to touch multiple ports
after an update, there will also be churn in the PLIST files, and
pkg_add will need to remove/reinstall files even if there was no
change to the contents.
