>Description:
As described in 5.4.7 of the porters handbook multiple distribution files can be used in the form of 
MASTER_SITES=  ftp://ftp.example1.com/:source1 \
 ftp://ftp.example2.com/:source2
DISTFILES=  source1.tar.gz:source1 \
 source2.tar.gz:source2

I have just tried applying this to the new github settings and found that it fails.

When multiple values are setup for GH_PROJECT and/or GH_TAGNAME the fetch command gets a mangled download link with the group name instead of the account/project/tag. I also tried with GH_ACCOUNT to match the groups with no benefit.

eg while the correct link would be -
https://nodeload.github.com/sambler/myblender/tarball/sambler-2.64.2?dummy=/blender-sambler-2.64.tar.gz
having GH_PROJECT=  myblender:base turns the link into -
https://nodeload.github.com/baseblender-sambler-2.64.tar.gz

While I don't need to use a separate GH_ACCOUNT for what I am doing I see that it could be required as well. The question there would be - Can project or tagname be setup with multiple sources or would all three need to be setup for grouping? I could see a single account and tagname being used with multiple project names to get the full sources needed, but I doubt multiple tags with one project would be usable.

Looking ahead - this may require a way to define which extracted tarball becomes WRKSRC. Maybe the DEFAULT group?

>How-To-Repeat:
The port I am working on isn't official but the files (without github changes) are available at http://redports.org/browser/sambler/graphics/blender-sambler

After removing MASTER_SITES DISTFILES FETCH_ARGS and WRKSRC I added -

USE_GITHUB= yes
GH_ACCOUNT= sambler
GH_PROJECT= myblender:base \
myblenderaddons:addons \
myblendercontrib:contrib \
myblendertranslations:trans
GH_TAGNAME= sambler-${PORTVERSION}.${PORTREVISION}:base \
addons-${PORTVERSION}.${PORTREVISION}:addons \
contrib-${PORTVERSION}.${PORTREVISION}:contrib \
translate-${PORTVERSION}.${PORTREVISION}:trans
