can someone explain to me how do I set up the latest bfgminer? If I do git clone I still get bfgminer 3.9 and if I wget the 4.5 tar and do ./autogen.sh I get not a git repository

so then I do

./configure
make

But it fails in the make process

make[2]: Entering directory `/home/jp/bfgminer-4.5.0-med/ccan.bfg'
make[2]: *** No rule to make target `../ccan-upstream/ccan/opt/helpers.c', needed by `../ccan-upstream/ccan/opt/libccan_a-helpers.o'.  Stop.
make[2]: Leaving directory `/home/jp/bfgminer-4.5.0-med/ccan.bfg'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/jp/bfgminer-4.5.0-med'

I am relatively new to linux
