Details:

I am/was trying to compile boswars on Arch Linux with AUR package at:
https://aur.archlinux.org/packages/boswars-svn/

I get:

http://lists.opensuse.org/opensuse-factory/2012-01/msg00265.html suggest that
it could be because boswars need lua5.1 not lua5.2 

Fedora seems to have applied the following patch to build with Lua 5.2:

Probably, a good fix would change the function detectLua in make.py, and would
detect if the system have Lua 5.1, 5.2 or both, and define some symbols, to
allow building the program in the two cases.

That said, I don't feel I know enough to make such a contribution.
