Some other package managers observe a distinction between "runtime" and "development" packages, with the latter having a "-dev" suffix. MacPorts does not observe such a distinction. All packages in MacPorts contain both the runtime and development parts, to the extent that each software package has those parts.

MacPorts does have port names with a "-devel" suffix, but they embody a completely unrelated concept. Ports with names not ending with "-devel" are typically for stable versions of software while ports with the "-devel" name suffix are for newer unstable versions.

Please choose one package manager and uninstall the other. We do not want to spend time diagnosing problems that were caused by installing software with multiple conflicting package managers.
