newbie: build.opensuse.org CentOS_7 i586 status unresolvable

The CentOS_7 i586 environment/VM at build.opensuse.org does initialize/setup properly. It fails with “unresolvable” before reading any of my project files. The html hover popup says “nothing provides gcc, nothing provides autoconf, …”. I could not find any URLs on how to fix, report, or troubleshoot this issue.

How can I report/troubleshoot/fix this issue?

thanks,
