I've not users this in quite a while, so I may be wrong here, but I think 
what you need is:


If gzip support is compiled in, it will automatically try to fetch 
dlroot.gz first and if it succeeds, it will uncompress and use it. The 
way you have configured it, it tries dlroot.gz.gz, which fails, so then 
it tried to load dlroot.gz as an uncompressed file.
