This definitely looks like a bug I fixed before, see <http://bugs.python.org/issue7724>. The patch should not be present in 2.7 and any of the active branches.

I can build hashlib just fine with the HEAD of the release26-maint branch, could you please test with 2.6.6?

BTW. In general it is better to file bugs at bugs.python.org instead of mailing them here, using the bugtracker ensures that your report doesn't get lost.
