Additionally, media-sound/sooperlooper does not have RDEPEND/DEPEND on sys-libs/ncurses.

The combination of the two looks good.

Fix build with sys-libs/ncurses[tinfo]

Merged two upstream commits into single patch file.

A different approach that uses pkg-config and only defaults to AC_CHECK_LIB when that fails.

This is the only correct solution, as anything but pkg-config will not scale. Personally, I would remove the subsequent AC_CHECK_LIB check too, because it adds no value really anymore.
