In order to build the paranormal plugin, which is being done automatically, libsdl is needed; according to configure.ac, in version >= 1.2.5. $ readelf -d /usr/lib/audacious/Visualization/libparanormal.so Dynamic section at offset 0x19b04 contains 27 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [libgtk-x11-2.0.so.0] 0x00000001 (NEEDED) Shared library: [libgobject-2.0.so.0] 0x00000001 (NEEDED) Shared library: [libglib-2.0.so.0] 0x00000001 (NEEDED) Shared library: [libSDL-1.2.so.0] [...] So this needs to be added to the ebuilds. Perhaps via USE flag?
Dependency added to 1.3.0_alpha1, thank you for your bug report.
