Hello, I had a look at the MCL package and found that it is very much focused on the MCL library but apparently does not feature the impala library that ships the implementation of mclgUnionv. Proof below, I compiled MCL myself and copied libimpala.a to the ocaml directory.
I am mostly clueless about ocaml. Does this help anyone to fix the problem or have a chat with the Debian maintainer of the mcl package? Uh - that's us. :o/ Steffen moeller@steffen-laptop-debian:~/git/med-team/pplacer/_build$ ocamlfind ocamlopt -ccopt -static -linkpkg -package batteries -package csv -package xmlm -package gsl -package
