The "tickets" are branches within the software repositories.  "master" is another branch; "master" is to git as "trunk" is to svn.

To get a particular branch, clone the repository and checkout that branch.  Then you need to tell your system that you want to use it, and build it:

# Clone the repo
git clone git://dev.lsstcorp.org/LSST/DMS/<package>.git

# Get the right branch
cd <package>
git checkout <branch>

# Use this version of that package
setup -j -r .

# Build the package so you can use it
scons
