Hi there!
I've done (actualy, long time ago) lua.eclass to ease maintenance of dev-lua
packages in a way of dev-ruby and dev-python packages (including TARGETS and
so).
All ebuilds in lua overlay is already ported to it (in basic way), although I
recently added GITHUB_* and BITBUCKET_* magic (like rubygems and perl CPAN
magic), and still not finished porting ebuilds to it (although, I maybe finish
it until tonight).
So, I posting it to review and comments. And to ask your opinion about it's
inclusion in the tree.
P.S. after few days (depends on comments in this thread) it may differ from
up-to-date version in overlay.

# @BLURB: An eclass for installing Lua packages with proper support for
multiple Lua slots.
# @DESCRIPTION:
# The Lua eclass is designed to allow an easier installation of Lua packages
# and their incorporation into the Gentoo Linux system.
#
# Currently available targets are:
# * lua51 - Lua (PUC-Rio) 5.1
# * lua52 - Lua (PUC-Rio) 5.2
# * lua53 - Lua (PUC-Rio) 5.3
# * luajit2 - LuaJIT 2.x
#
# This eclass does not define the implementation of the configure,
# compile, test, or install phases. Instead, the default phases are
# used. Specific implementations of these phases can be provided in
# the ebuild either to be run for each Lua implementation, or for all
# Lua implementations, as follows:
#
# * each_lua_configure
# * all_lua_configure
# @ECLASS-VARIABLE: LUA_COMPAT
# @REQUIRED
# @DESCRIPTION:
# This variable contains a space separated list of targets (see above) a package
# is compatible to. It must be set before the `inherit' call.
: ${LUA_COMPAT:=lua51 lua52 lua53 luajit2}
# @ECLASS-VARIABLE: LUA_PATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# A String or Array of filenames of patches to apply to all implementations.
# @ECLASS-VARIABLE: LUA_OPTIONAL
# @DESCRIPTION:
# Set the value to "yes" to make the dependency on a Lua interpreter
# optional and then lua_implementations_depend() to help populate
# DEPEND and RDEPEND.
# @ECLASS-VARIABLE: LUA_S
# @DEFAULT_UNSET
# @DESCRIPTION:
# If defined this variable determines the source directory name after
# unpacking. This defaults to the name of the package. Note that this
# variable supports a wildcard mechanism to help with github tarballs
# that contain the commit hash as part of the directory name.
# @ECLASS-VARIABLE: LUA_QA_ALLOWED_LIBS
# @DEFAULT_UNSET
# @DESCRIPTION:
# If defined this variable contains a whitelist of shared objects that
# are allowed to exist even if they don't link to liblua. This avoids
# the QA check that makes this mandatory. This is most likely not what
# you are looking for if you get the related "Missing links" QA warning,
# since the proper fix is almost always to make sure the shared object
# is linked against liblua. There are cases were this is not the case
# and the shared object is generic code to be used in some other way.
# When set this argument is passed to "grep -E" to remove reporting of
# these shared objects.
