Dear Sirs

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)/.
I'm not talking about gsl-shell that needs luajit.

I'm working in MacOSX with minimals.
My LUAINPUTS are:

 LUAINPUTS  =
".;$TEXINPUTS;$TEXMF/scripts/context/lua//;/usr/local/lib/lua/5.2//",
 CLUAINPUTS      =
".;$SELFAUTOLOC/lib/{context,luatex,}/lua//;/usr/local/lib/lua/5.2//",

>ls /usr/local/lib/lua/5.2
GSLdefs2.lua
alien_c.la
alien_c.so
gsl.lua

The GSL library is called using the Alien. If i try:



 \starttext

      \enabletrackers[resolvers.libraries]

      \startluacode
          print("LUAINPUTS",os.getenv("LUAINPUTS"))

          require("alien") ;
      \stopluacode

 \stoptext

"""
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  .
