Bugzilla Bug 208172

Layman helps the user manage different overlays.  A quick overview of those
available (layman -L) shows that three (possibly four) different content
tracking packages are used, rsync, subversion, Git (and possibly Tar?).

I tried adding an overlay that uses Git, but was told that I didn't have Git
installed.

I think it would be useful to have appropriate USE flags for layman to pull in
Git/rsync/subversion as required by the user.

Reproducible: Always

Steps to Reproduce:
1. emerge layman
2. layman -L
3. layman -a mpd

Actual Results:  
If dev-util/git isn't already installed....

* Failed to add overlay "mpd".
* Error was: Binary /usr/bin/git seems to be missing! Overlay type "git" not
supported. Did you emerge dev-util/git?


Expected Results:  
Nice if you could...

echo 'app-portage/layman [git | subversion | rsync]' >>
/etc/portage/package.use
emerge layman
layman -a mpd

...and the overlay would be installed because the relevant tracking package was
pulled in when layman was installed.

That's what the message is for there; we are not adding dependencies to the
ebuild.

Fairy-muff.

I did read the message and am aware I could install Git by hand, just thought
that was the point of having USE flags.

Well, I see you point, but we've been getting bugs to the opposite effect when
the dependencies were there, so... can't satisfy everyone I guess - so instead
the messages have been improved to provide the info in a friendly way when you
don't have the needed VCS app installed.

Thanks,

Also, looking at the ebuild there is a test for subversion in there, so why not
the others?

Well since "most available overlays are offered via dev-util/subversion",
that's it.
