ubu 11.04 (natty) ships boost 1.42, so yes.
  http://packages.ubuntu.com/libboost

(fwiw gpsdrive is one of mine)

Since it's a header file I wildly guess that's referring to an embedded
version number? if so, nice that gcc is warming about such things but just
a false positive.

it would seem that a variable in CMakeLists.txt is being left empty so
$PATHNAME/lib$LIBNAME.so collapses to ""/lib"".so. Error in cmake control
