I took a look at dendrite, and it looks like it needs some 
dependencies. In the build output I saw a bunch of:

src/github.com/matrix-org/dendrite/internal/consumers.go:21:2: 
cannot find package "github.com/Shopify/sarama" in any of:
	/gnu/store/cb9kqjg7m6xk1wz7ap8as792fd5kcmd2-go-1.14.10/src/github.com/Shopify/sarama 
	(from $GOROOT)
	/tmp/guix-build-dendrite-0.3.1.drv-0/src/github.com/Shopify/sarama 
	(from $GOPATH)
src/github.com/matrix-org/dendrite/appservice/appservice.go:23:2: 
cannot find package "github.com/gorilla/mux" in any of:
	/gnu/store/cb9kqjg7m6xk1wz7ap8as792fd5kcmd2-go-1.14.10/src/github.com/gorilla/mux 
	(from $GOROOT)
	/tmp/guix-build-dendrite-0.3.1.drv-0/src/github.com/gorilla/mux 
	(from $GOPATH)
...

From what I can see of the other Go packages in Guix, each of the 
dependencies needs to be added to the propagated-inputs of the 
dendrite package to make it build.

I don't think we have all of these dependencies packaged in Guix 
at the moment, so you will have to write some package definitions 
for these dependencies before you can package dendrite. I'm not 
up-to-date on the state of Go in Guix, but I think there are some 
patches for a Go importer floating around on the mailing list, if 
you wanted to try automatically importing package definitions.

I hope that helps,

Carlo
