Seems to work over here:

$ guix shell --pure minetest minetest-mesecons
[ in the GUI: ‘Select Mods’ ]
[ GUI: ]
+ mesecons
+ Minetest Game mods

[ in the GUI: select +mesecons ]
[ ...]

Make sure to install Minetest and its mods in the same profile, and to 
log out and in again if it's not done with "guix shell" or "guix 
environment --ad-hoc" but with "guix home" or "guix install", such that 
Guix can set appropriate environment variables (MINETEST_MOD_PATH).

minetest-mod-build-system does this too, in 'mod-install-plan'
