solbuild can't use proxy

[MrBn100ful]

Hi,
i can't build package using solbuild with a proxy.

When i try to make the package, it try to download the tarball from the source but the proxy block the download.
I have the proxy in gnome-control-center.
i think solbuild use curl so i have made an alias, so when i run 'curl' it run' curl -x myproxy' but it still doesent work.
I have also try with the command 'export http_proxy='myproxy'' and 'export https_proxy='myproxy'' but it still doesent work.

the only solution i have found is to remove sudo from Makefile.common and connect to the root user and use the command 'export http_proxy='myproxy'' and 'export https_proxy='myproxy''.

I am using the last version of Solus 4.

Thanks.
