It does know `build-dep' for a while now; it was first introduced here:

_aptitude does more than _apt-get. If the second <tab> doesn't take as
long as the first, you probably got caching enabled via zstyle.

My installation is also from the git repo:
% uname -srm
Linux 2.6.32-5-686 i686
% print $ZSH_VERSION
% print $ZSH_PATCHLEVEL
% sudo aptitude <tab>
- aptitude command -
autoclean -- erase old downloaded package files.
build-dep -- install the build-dependencies of packages.
changelog -- view a package's changelog.
Are you sure you don't have two competing versions of zsh installed?
Then it may be possible that "print $ZSH_VERSION" and "zsh --version"
would yield different results.

nothing left to add, but when there is nothing left to take away.
