scmxx-0.6.0 ebuild is broken (failed to download source). scmxx-0.6.0 tarballs was moved under old directory. Latest stable version is 0.6.3.5, i'm testing it now (i'm simply copy scmxx-0.6.0.ebuild to scmxx-0.6.3.5.ebuild)
I fixed the location, thanks for the report. I have also added an ebuild for 0.6.3.5, but I can't test it because I don't have a Siemens phone. Please test it so that I could mark it stable. Thanks!
