Hi Eric, Khem,
  I am also having very similar thoughts here. My fedora does not have 
readline_d.so installed, and that is not a problem for host gdb.

The install issue you are seeing is due to python-native which is used 
in the nativesdk install process, it is expecting "pydebug" enabled 
in the native version also. And I could not get that patch applied to the
python-native successfully (another build issue).

Anyways, we 1st need to understand, how gdb in mainline distros like fedora 
is able to work fine without having the debug python modules installed.

Thanks,
Nitin
