The lua version on the OpenWRT device that is being used is Lua 5.1.5.

Trying with the "--with-liblua=included" option, it tried to compile 
liblua, however it still failed with the attached error log.

But it seems some progress were made. Do you have any other suggestions 
I could try?

Thanks Daniel
