No need to feel sorry for; I just wanted to state it clear, might went overboard.

two thoughts:

   python is well known for not cross compiling well.  You may be in new
Still must work somehow and I haven't experienced that many issues with python compiled things yet; just gpsd. Cross compiling itself can be tricky.

   I am not quite following, but it may be that build code setting
   HOST_DIR does not grasp the concept that if it is under DESTDIR, then
   that part should be removed to get a DESTDIR relative path.  I think
   there may be trouble from mixing DESTDIR-aware build code from code
   that is not really aware but is using a path that has DESTDIR in it.

There could be a check whether DESTDIR and python_libdir contain the same path (a huge part of it). At least for cross compiling with buildroot it would work.

In fact python and its library is always under /lib|/usr/lib|/usr/lib32|/usr/lib64 isnt it? So why does it need to check from where it is called instead of some other work arounds?

I don't know which environment variables you can get while using scons, may there is one that suits better for the purpose of finding the python path?
