acxz [1] filed a request to merge pagmo2 [2] into pagmo [3]: The upstream url for the `pagmo` package is not supported anymore. This package (`pagmo2`) tracks the currently development for the upstream pagmo project. As such I would like for this package to be merged into the outdated `pagmo` package, so that the namespaces can be resolved. Basically delete this package and update `pagmo` with the new upstream url.
