IC. Indeed I missed that a different package was build. So I agree, this
is not a bug.

But i suggest to emit a more verbose message in this case, e.g.:

guix build: package 'gpgmepp'
will not be build, since it       <<--- new
has been superseded by 'gpgme'.
'gpgme' will be build instead.    <<--- new

Or (maybe easier to implement:
guix build: package 'gpgmepp' has been superseded by 'gpgme'.
Thus 'gpgme' will be build instead of 'gpgmepp'.        <<--- new
