[Luarocks-developers] Trouble upgrading to LuaRocks 2.2.0-2

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

  I saw the announcement of LuaRocks 2.2.0-2.  I tried updating (using
"luarocks install luarocks") and the short version of it---I ended up having
to nuke *just about everything* (I kept /usr/local/etc/luarocks) related to
luarocks and start over [1].  I do have the latest git repo cloned, and,
wanting luarocks installed in my local
$HOME/.luarocks tree, made sure the configuration is configured as such.

  Running from ~/apps/luarocks/src:

[spc]lucy:~/apps/luarocks/src>./bin/luarocks

Okay, so then I:

Okay.  Now, when I attempt to use $HOME/.luarocks/bin/luarocks:

I'm concerned about two things:

	1) that luarocks/site_config.lua wasn't copied.
	2) that it's not defaulting to /usr/local/etc/luarocks.

I don't know if there's an actual bug here or what, but this upgrade has
been a rather nasty one.

[1]	It may have had something to do with initially installing LuaRocks
	via source a long time ago, then switching to updating via luarocks
	itself.  I also use a local tree in $HOME/.luarocks, with
	appropriate $LUA_PATH and $LUA_CPATH pointing there first before
	hitting /usr/local directories for Lua modules.

	That's a guess on my part since I mucked up a few instances of
	LuaRocks on several machines (sadly, I wasn't paying attention to
	which window what logged into what machine), and I'm willing to
	admit that the entire thing might have been my fault at some level.
