Arnaldo,
Looks like some define is missing during the generation of the python support.
If you don't have newt then it fails to compile:
$ make
Makefile:430: newt not found, disables TUI support. Please install
newt-devel or libnewt-dev
PERF_VERSION = 2.6.38
Makefile:430: newt not found, disables TUI support. Please install
newt-devel or libnewt-dev
...
GEN perf-archive
GEN python/perf.so
In file included from util/evsel.h:10,
from util/python.c:6:
util/hist.h:105: fatal error: newt.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1

I encountered the same problem. See my fix below.

Subject: [PATCH] perf tools: Fix NO_NEWT=1 python build error
Fix the following build error:
GEN python/perf.so
In file included from util/evsel.h:10,
from util/python.c:6:
util/hist.h:106:18: error: newt.h: No such file or directory
error: command 'x86_64-pc-linux-gnu-gcc' failed with exit status 1
make: *** [python/perf.so] Error 1
by passing BASIC_CFLAGS to setup.py. BASIC_CFLAGS variable contains
the -DNO_NEWT_SUPPORT switch which prevents building python c
extension with newt.
