   First of all, what you refer to as "ports" here are known as
"packages" in the NetBSD world since "ports" was already being used
to refer to "ports of the OS to different platforms".

   More specifically, yes, the pythonXY-pth packages are built
against the GNU pth library to provide thread support and should
suffice for NetBSD 1.6.x. As Donn suggested, if you upgrade to a
later version (1.6X or 2.0*) you can just use the python package
with native pthread support. If you can't find it prebuilt, look
into using pkgsrc, which should be fairly painless (and quite
convenient.)
