py-pip fails when staging

[shabbyrobe@…]

Using 10.6.6. I've just done a selfupdate and tried to install py-pip and it gives me this:

--->  Computing dependencies for py-pip
--->  Fetching py-pip
--->  Verifying checksum(s) for py-pip
--->  Extracting py-pip
--->  Configuring py-pip
--->  Building py-pip
--->  Staging py-pip into destroot

The log file mentioned above is pretty huge, so here's the last bit if it helps. I'll attach the full thing:
