lua5_5_pc_typo:
# liblua5.5-dev installs a pkgconfig/lua5.5.pc file that contains a typo
# in the version that prevents `lib_name_include=lua5.5` from being set.
#
# Typo fix would be:
# ```diff
# - version=5.5.#define LUA_VERSION_RELEASE LUAI_TOSTR(LUA_VERSION_RELEASE_N)
# - lib_name_include=lua5.5
# + version=5.5.0
# + lib_name_include=lua5.5
# ```
#
# This causes the luarocks LUA_INCDIR variable to be undefined, which
# results in failures when calling `luarocks --lua-version=5.5 make`.
#
# `apt-get install luarocks` delivers v3.8.0, which should be updated
# to luarocks >= v3.13 to support lua5.5.
