# NOTE: neko's install.n checks for availability of optional libraries,
# prompting the user for a path if the library is not found.
# We disable this checking (with patch), and care for availability
# by using dependencies. The .ndlls will be built if the dependency
# is installed, but themselves installed only if the respecive
# USE flag is set.
