./configure: Permission denied for bad archives

[shagren]

I had error like when install optipng-bin module

/bin/sh: ./configure: Permission denied

I spent some time and found where is the problem:

1. When I add new module which use bin-builds it`s try to download and install some tar.gz file from sourceforge.net
2. But sourceforge.net had some maitenance issues at that moment and return some html instead tar.gz file which download module store as filename.tar.gz
3. Then decompress-tar return empty files list to decompress-targz and last pass this list to decompress
4. bin-builts think thats all right and try to execute autoconf and failed.

I think must be test for this situation. But I do not sure in which module:

• decompress
• decompress-tar
• download
• bin-build
• tar-stream
