It shows that py-fastTSNE has 0.2.14, but it doesn't exist, in reality: https://portscout.freebsd.org/yuri@freebsd.org.html
Maintainer reset.
For example, for graphics/gifski portscout shows that v4.3.5 is available when the repository https://github.com/ImageOptim/gifski/tags doesn't have such tag.
The link shown for graphics/gifski is bogus: https://codeload.github.com/https://api.github.com/repos/kornelski/rust-ffmpeg-sys-1/tarball/refs/tags/v4.3.5?dummy=/:_cargo_git0 The link comes from some entirely different project.
