Hi,

The log says:

Failed to build these modules:
binascii           readline

And when building binascii it says:

Include/pyport.h:849:2: error: #error "LONG_BIT definition appears wrong 
for platform (bad gcc/glibc config?)."


The fact that also readline fails to build explains why I can't use the 
cursor keys when using the Python interpreter on my ARM board.

The full log is here (copy and paste to a local file):
