Ok, our currently (upcoming) debian ocaml policy state that debian programs _and_ library should have depends like "ocaml (>= ver) (<< ver+1)" (I know not all ocaml debian packages, including some of mines, fullfill this requirement). So the admin can just use dpkg. This obviuosly only apply when dependencies are debianized, for the other cases see below. > Why?

I can set the default of findlib to install stuff there, but I can't surely impose to all third part softwares to use findlib neither can I impose to use the default findlib values ...

Ok, but the problem is how we can implement this tool: we can't just use locate, the better that comes in my mind is findlib (try 'ocamlfind list'), but we have to impose the use of findlib to all debian packages!

Ok, but we (the sysadm) can't blame us as debian, he will have to blame the third part installation routine that doesn't install in a versioned subdir. We DD can just support versioned directories in /usr/local, nothing more. Cheers. -- Stefano Zacchiroli - undergraduate student of CS @ Univ.
