Hi, dh-lisp 0.5 would recognize FASL objects built by [11]ECL as Clisp's FASLs and add a dependency on Clisp automatically, if a Debian package contains FASLs of ECL. (so be sure to use the -d switch with dh-lisp if you deliver ECL's FASLs in your packages) dh-lisp 0.6, as I just pushed it to [12]my repository -- although I have not released it yet -- does solve this misfeature by better detecting file types and explicitly ignoring ECLs files. There is code in dh-lisp to automatically add dependencies for ECL, but it is commented out, because there is (should be) a better way to handle it: each ECL binary links with libecl.so, so the ecl package -- once it comes into Debian -- should bring a shlibs description and dh_shlibdeps should better solve this dependency. In case somebody proves me wrong and it turns out that shlibs don't work well in this case, I can just uncomment this code. ;-) However, the usual features of dh-lisp also work for ECL: installation of the implementation and their maintainer scripts and (of course) installing CL libraries. 11. http://ecls.sf.net/ 12. http://cl-debian.alioth.debian.org/repository/rvb René
