contribs on mac are corrupted.

Hello,

I can't able to compile vlmc because the zip files (frei0r-effects-macosx.zip.zip and libvlc-2.0.4-macosx.zip, may be another) seems corrupted. Unzip can not uncompress it. Unzip returns this message :

$ unzip frei0r-effects-macosx.zip 
Archive:  frei0r-effects-macosx.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of frei0r-effects-macosx.zip or
        frei0r-effects-macosx.zip.zip, and cannot find frei0r-effects-macosx.zip.ZIP, period.

Regards,
