libgnomeprint-2.10.0 depends on libgnomecups-0.2.0, but this dependency is not listed. checking for libgnomecups-1.0 >= 0.2.0... Requested 'libgnomecups-1.0 >= 0.2.0' but version of libgnomecups is 0.1.14 configure: error: Library requirements (libgnomecups-1.0 >= 0.2.0) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
The ebuild of net-print/libgnomecups-0.1.14 works for net-print/libgnomecups-0.2.0 as well.
