ports/lang/python27 failing to build (_ctypes.so no such file)

[draeath]

Hello,

I am attempting to build the python27 port as a dependency for
virtualbox-ose-additions and am running into a build error. I am running
FreeBSD 10.0, with /usr/ports coming from SVN head (currently Revision
354006). I'm afraid I don't know what other information I need to provide
to you - though I would be happy to provide it as required (I may need a
tiny bit of handholding to find it, as I am not terribly at home in FreeBSD)

uname -a, as I see this requested for problem reports:
FreeBSD fbsdvm 10.0-RELEASE-p2 FreeBSD 10.0-RELEASE-p2 #0: Tue Apr 29
17:06:01 UTC 2014
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC
amd64

The build error I am seeing is:
