I’m afraid you are suffering from the `libstd++` problem discussed [here](https://discourse.julialang.org/t/failing-to-register-new-version-because/82346/3) and while [#45582](https://github.com/JuliaLang/julia/pull/45582) is not solved, your option is to install GMT with a package manager or build it yourself (not difficult). See general instructions for Linux [here](https://github.com/GenericMappingTools/gmt/blob/master/INSTALL.md#linux)
