"rpm -ba" is very old. I think it's been at least since 2002 that "-ba" was supported by rpm.
I believe bdist_rpm is calling "rpmbuild -ba", and if that doesn't exist, then "rpm -ba" is a transition strategy until all systems supported "rpmbuild". This transition period should be over. Unfortunately today it's far more likely that "rpm -ba" will not be what you want to call, but "rpm" will almost always be found, giving this error.
Most systems (certain RedHat based) ship rpmbuild as a separate command. RedHat installs it via the rpm-build package.
I'd suggest just switching bdist_rpm to always use rpmbuild. Then at least the error would be that rpmbuild isn't found. |
