I've got a spec file which (edited) says: BuildRequires: perl BuildRequires: perl-ExtUtils-Embed Requires: %(perl -MExtUtils::Embed -e ldopts | egrep -o '/[^[:space:]]*CORE' | head -1) It fails occasionally (but by no means always) in Koji, as for example here: http://koji.fedoraproject.org/koji/taskinfo?taskID=510764 The failure seems to be because perl-ExtUtils-Embed isn't installed by the time we evaluate the expression in the 'Requires' statement. So I guess we can't have a spec file which evaluates an expression which needs some BR's to work. Is there some standard way to work around this problem?
