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.

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?
