According to your log you have numa headers, but don't heave numa library
to link against.

#define HAVE_NUMA_H 1
#define HAVE_NUMAIF_H 1

NUMA_CPPFLAGS=''
NUMA_LIBS=''

Both should come from numactl devel package. To unblock compilation
you can edit include/config.h and set any numa related options to 0.
Then make clean && make should work.

Jan
