Is there a way to call external lua modules inside luatex. In particular I would like to call gsl libray using a gsl-lua binding (http://www.stefanom.org/devel/gsl-lua)/.
from this site
""" gsl-lua has been tested with Lua 5.1.4 and LuaJIT 2.0 (beta 6). """
Latest luatex uses lua 5.2.1 and is not compatible with lua 5.1.4 .
