 Replying to [comment:14 ryandesign@…]:
 > Ports should be for specific versions, as Joshua said -- even -devel
 ports. You're free to update the -devel port at any time to a newer
 version, but users must be able to consistently install the same version
 of software.

 When no branch is specified (and thus a default branch is used), users
 will always install the same *version*, but not necessarily the same
 *revision* (of that version). Quoting from the MacPorts Guide:

 git.branch
 Optional tag for fetching with git, this specifies a branch (or other
 commit-ish) that git should checkout. Note that any branch besides HEAD
 should be prefixed by origin/.

 Default: none

 Example:

 git.branch             72bf1c8
 git.branch             origin/next

 The second example checks out the latest revision on the specified branch.
 At least ten other ports do exactly the same: specifying a branch name and
 not a specific revision. Branch names, however, often correspond to
 versions. Therefore, by specifying a branch, users will always get the
 same version but clearly not the same revision of that version (unless, of
 course, not commits are being made on that branch). In this particular
 case, the problem is fixed by simply updating the git.branch field to
 "origin/master". Should I submit an update portfile or is possible for you
 do the update manually?
