error sbo slackrepo build

I have an issue trying to build many programs from SBO. When I download files from SourceForge, they end up with ?viasf=1, and when trying to unzip them, it can't find the file. For example, the downloaded code is saved with the name 107308-Almond-rounded.zip?viasf=1, and it was expected to be 107308-Almond-rounded.zip.

Any suggestions?
