Hi,
I'm trying to build a rootfs with python 2.7. using buildroot version 2016.05. On the target here is what I get:
Welcome to Buildroot
buildroot login: root
login[1338]: root login on 'console'
# python
Could not find platform independent libraries <prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site
# export PYTHONHOME=/usr
# python
ImportError: No module named site
# ls /usr/lib/python2.7/
LICENSE.txt encodings logging sysconfigdata
compiler ensurepip multiprocessing unittest
config hotshot pdb.doc wsgiref
ctypes importlib plat-linux2 wsgiref.egg-info
distutils json site-packages
email lib-dynload sqlite3
all the standard library files are missing, including site.py.
Digging in the build process, I believe there is an error in the install process :

Sorry for the noise ^^ One of my packages does that in its makefile :
find $(DESTDIR) -name *.py -exec rm {} \;
find $(DESTDIR) -name *.pyc -exec rm {} \;
find $(DESTDIR) -name *.pyo -exec chmod +x {} \;
In OpenEmbedded it causes no harm, but in buildroot, it causes every .py{c} to disappear

It would be good if you had provided a bit more context here.
But I guess the reason is because we remove *.pyo files in Buildroot,
so if you remove *.py, *.pyc in your package, and Buildroot removes
*.pyo, there's nothing left.
