Some days ago the new version 2.3 of xindy was released. “xindy is an index processor that can be used to generate book-like indexes for arbitrary document-preparation systems. This includes systems such as TeX and LaTeX, the roff-family, SGML/XML-based systems (e.g., HTML) that process some kind of text and generate indexing information.” It has several advantages compare to MakeIndex like better internationalization and customizability. In the new version it is possible to use an external clisp compiler, although I was not able to do it successfully. There is an error in the configure script, one has to add enable to the clisp path and exectable changing options (eg --enable-clisp-dir=/usr/lib64/clisp).

I added an ebuild to Gentoo Bugzilla.
