Dear sirs I would like to try luatex lunatic ( http://wiki.contextgarden.net/User:Luigi.scarso/luatex_lunatic) but i d'ont find the luatex-0.42. I'm looking in https://foundry.supelec.fr/frs/?group_id=10&release_id=406#luatex-beta-0.76.0-title-content
I've been looking for a way to simulate data with different distributions (normal, poisson, exponential, etc.) in the .tex file. The use of GSL library is a good option, but it seems impossible to import in luatex. Another way is using the R-statistical through filter module***, which seems to work well in luatex. At this time I would try to import the GSL functions through python script. For that i think that i need the older luatex 0.42 but I don't find that.
*** \defineexternalfilter [R] [ filtercommand={R CMD BATCH -q --save --restore \externalfilterinputfile\space \externalfilteroutputfile}, output=\externalfilterbasefile.out, directory=output, readcommand=\typefile, read=no, cache=yes, ]

I'm sorry to say that I cannot help you with luatex lunatic, luatex 0.42 is too old and today there are other ways to build wrappers . I can suggest to see SWIG (http://www.swig.org), there is a very good section on Lua. In any case the filter module that you use is often a reliable alternative to connect to external programs, so the problem is often to be sure to have a good program. In your case you can also write a python script that uses that gsl module (if there is such module, I don't know exactly) and then call python by mean of the filter module.
