Hi, The problem here is not with the file names, but that you don't actually get the same file every time. The file is generated by the server on-the-fly, and the mtimes of the files in the download you get depend on the precise moment you download it, as you can tell by inspecting the output of
tar tvf $download This is fundamentally incompatible with any package manager that checks that source archives are downloaded correctly. The original website http://lancre.ribbrock.org/en/binabit_en/wmsmpmon_en/wmsmpmon-changelog_en.html appears to link to a stable archive that you should be able to use instead.
