Calcium,
Thanks for the report!
In future, please submit separate issues separately, it helps keep
discussion, er, separate. It's easier to merge issues than to
split them.
Can't (specification->package "package@version:output")
Short answer: it is not intended to work. Use
The syntaxe to specify a package version and desired output
only works on guix install package@version:output
guix remove package@version:output doesn't works
guix remove package@version doesn't works
(specification->package "package@version") works
(specification->package "package:output")
