Hello,
1/ Missing dependency
I noticed that there is a missing dependency of libdbus-ocaml-dev (v. 0.29) on libdbus-1-dev on debian 7. Otherwise during a build, there is a linking problem:
/usr/bin/ld: cannot find -ldbus-1
collect2: error: ld returned 1 exit status
File "caml_startup", line 1, characters 0-1:
Error: Error during linking
