Hi,

actually that build log was for Ubuntu 12.04; the error in sid/1.49
was the same but different (and uglier!) as seen in a later post in the
ML thread:
  http://lists.debian.org/debian-gis/2012/06/msg00002.html

right, Aron on the debian-gis ML helped me figure out the way to get
that to happen forcibly from within cmake, so now it links successfully.


Thanks for reminding me about the build-depends too, I'd neglected that.

libboost-filesystem1.49-dev depends on libboost-system1.49-dev;
shouldn't one of them depend on libboost-thread1.49-dev too, if that
is in fact the case?


cheers,
