Hi,
I made the following changes
$ git diff

I got a libpyledger.so, but upon doing an import libpyledger in python, I
get the following error
ImportError: ./libpyledger.so: undefined symbol: __gmpq_add
Any ideas about this? I have absolutely no idea about this since I'm not a
C++ programmer.
Thanks,
cb
