Hi Ken Takata

Sorry for trouble you again. This error occurred again.

----------------------------
Error is:
The --with-python-config-dir=/usr/local/lib/python2.7/config has been set, but 
vim/Makefile still use the /usr as the PYTHON_HOME:

gcc -c -I. -Iproto -DHAVE_CONFIG_H     -g -O2 -U_FORTIFY_SOURCE 
-D_FORTIFY_SOURCE=1       -I/usr/include/python2.7 -DPYTHON_HOME='"/usr"' 
-pthread -fPIE  -o objects/if_python.o if_python.c
if_python.c:67:20: fatal error: Python.h: No such file or directory
 #include <Python.h>
                    ^
compilation terminated.
make[1]: *** [objects/if_python.o] Error 1
make[1]: Leaving directory `/home/marslo/.vim/vimsrc/src'
make: *** [first] Error 2
