Thank you for the LUA_COMPAT_MODULE trick and for the links, worth
reading! :-)
In attachment the submitted updated rockspec for lrandom:
- lrandom-20101118-1.rockspec compatible with lua >= 5.1, < 5.3
- lrandom-20120430-1.rockspec compatible with lua ~> 5.2
It is worth noting:
1. the current lrandom rockspecs share exactly the same url! So I did
not update older rockspecs and I think they should be removed unless
someone has url to the previous lrandom versions [1] ;
2. the md5 of the 5.1 lrandom changed, as mentioned by Philipp [2] ;
3. the lrandom license is actually not only "Public domain" but
"Public domain + BSD 3-Clause" [3]
4. because of the minor change between the versions 5.2 and 5.1 of
lrandom (see in attachement), do you think keeping only
lrandom-20101118-1.rockspec is enough ?
The attached rockspec includes updated md5 and license. Running lrandom
test.lua worked here with lua 5.2 for both rockspec.
Thanks in advance for further comments or for the update if it is OK.

[1] I think the upstream lrandom.tar.gz for lua 5.1 simply got
overwritten over updates, without reflecting change in tarball name or url.
[2] probably due to an unnoticed upstream update.
[3] lrandom actually compiles with two files: lrandom.c (Public domain)
and random.c (BSD 3-Clause)
