Hi Efraim,

I don't know what you mean with "so it doesn't have to be updated"? I
mean changing the package definition is an update?

Also, I don't know what your intention with "version-major+minor" is?
On core-updates the current version of gnome is "3.24.3".
Then (version-major+minor gnome-version) would still evaluate to 3.24,
which IS too big, 3.22 is the maximum accepted version. 

Let me explain a bit more: With adding "--with-gnome=3.22" we are
pretending the configure-script that we will use gnome-3.22, although
we still use the latest version (To be precise, we use gtk+, but that
seams to report the gnome-version with pkg-config). 

This version number is then used to search in the directory

/tmp/guix-build-arc-theme-20170302.drv-0/arc-theme-20170302/common/gtk-3.0

the matching "major.minor" version, choosing the right theme.

3.22 is already symlinking to 3.20, and that is the highest available
real directory.

So we might get wrong look&feel here, because it is not adapted to
GNOME 3.24. But there is no further development upstream anyway. If it
doesn't look totally malformed, we can use it like that. My disk is a
bit full, I can't do a vm-image with it currently.

Björn
