net-print/gnome-cupe-manager or net-print/libgnomecups should depend on recent cups version. Now, when I had too old cups I got something like "ippNewRequest function is not defined". As I see, net-print/libgnomecups does not specify version of cups to depend on. Reproducible: Always Steps to Reproduce: 1. Try to emerge gnome-cups-manager with ~ two years old cups installed Actual Results: During configure phase emerge fails with "ippNewRequest is not defined". Expected Results: Successful upgrade of gnome-cups-manager.
indeed, no version in a dep is bad. Set 1.3.8 as minimum version since that's what we have in tree. Thanks for reporting.
