libsmtp-0.8 (and 0.8.5, has new version dated 2006-06-27) does not support >=glib-2.0 it uses old glib-config to determine include path and lib path, but its dependencies contains: DEPEND="virtual/libc dev-libs/glib" should be: DEPEND="virtual/libc <dev-libs/glib-2" Reproducible: Always
Fixed, thanks
