RFE: Improve messaging when `rpmspec` is missing on an RPM-based distro
On OpenSUSE, rpmspec
- i.e. the rpm-build
package - is not installed by default. Because of this, commands like apkg build-dep
fail with a pretty vague
Command not found: rpmspec -P <...>
from which it is not immediately obvious whether it's an issue with the package specification, or something is missing for apkg
itself to work. I would suggest adding a message to lead the user to install rpm-build
and tell them it's required for apkg
to work correctly on an RPM-based distro.
