#45501: git-flow: Eliminate dependency on git
--------------------------+--------------------------------
 Reporter:  verwymeren@…  |      Owner:  macports-tickets@…
     Type:  request       |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.3.2
 Keywords:                |       Port:  git-flow
--------------------------+--------------------------------
 git-flow currently forces installation of the MacPorts git port. Since
 MacPorts requires Xcode be installed and Xcode provides git is this
 dependency necessary anymore? It would be great if the installation of git
 was optional when installing git-flow.
