If you have git installed, and you are trying to upgrade it, you may have problems.  The scmgit-docs package dependency requires some DocBook files that aren’t always accessible.  If you do run into this problem, there’s 3 separate options:

• You can just install scmgit-base and ignore scmgit-docs.  The program ‘git’ still runs.
• You can download the prebuilt DocBook files separately.
• You can rebuild some XML-related dependent files and then rebuild without issue.
