As the last successful emerge was on 25. October it must have something to do with that commit: https://cgit.freedesktop.org/cairo/commit/?id=eb5232002b16193d5ba6c1450d80616914fd9917 gl: Treat GLES v2 as a separate flavor from GLES v3HEADmaster To support differentiating between GLES v2 and v3, rename the flavor enum to be version specific, as CAIRO_GL_FLAVOR_ES2. Then, when GLES v3 support is introduced we can add it as a distinct flavor enum (i.e. CAIRO_GL_FLAVOR_ES3). Signed-off-by: Bryce Harrington <bryce@osg.samsung.com>

Thank you for diagnosing and fixing the bug. Please contribute the patch upstream by mailing it to cairo@cairographics.org. For a variety of reasons we prefer not to patch live ebuilds. Most of all because when the bug is actually fixed upstream, the build will be broken a second time.
