TBB nightly build failure: https-everywhere is using python2.7
When trying to build the current TBB nightly, the build stops during the step "Starting Bundling+Localization of Linux Bundle (4/4 for Linux)".
The file gitian-builder/var/build.log ends with this error:
+ cd https-everywhere
+ rm -f .git/refs/heads/master
+ ./makexpi.sh
./makexpi.sh: 98: python2.7: not found
ERROR: Validation of rulesets failed.
It seems to be related with the change from https-everywhere version 3.4.5 to 3.5. The makexpi.sh script in the new version explicitely uses python2.7, but Ubuntu Lucid has python 2.6.
