 sounds like complete twaddle, to me :)

 ... kick out of a build because the function's missing, yes.
 try to install versions of a library to detect the required minimum?
 i'll see it when i believe it.

 nope.

 nope - because there's a function missing.

 how the heck he managed to get it to work i really don't know.
 i think he built it on sarge or something.

 a rebuild still shows Depends: liblcms1 >= 1.08
 
 which is why i'm complaining to this guy because he doesn't understand
 that there's a problem.

 yehh, i've already installed liblcms1.15 to get working with the
 package, otherwise i would.

 and i need a working scribus-ng more than i need the maintainer to
 understand the problem.
