I have a problem similar to this post: Install python module to non default version of python on Mac, so I am aware of those solutions, but they do not work for me.
I am installing M2Crypto on CentOS, which means I much use fedora_setup.sh build followed by fedora_setup.sh install in order to install on my architecture.
Unfortunately, the default Python version is 2.6, but I use 2.7. How do I execute the build and install commands so that they build and install to Python2.7 site-packages? Is there a simple command I don't know? I've been searching around here: http://docs.python.org/2/install/ in the Python Docs, but I don't see anything about .sh scripts?
This was an incredibly difficult answer to come by, but the support team at Webfaction where I am hosted were spectacular in assisting me. Directly from the support I was given:
First build swig,
wget http://prdownloads.sourceforge.net/swig/swig-2.0.8.tar.gz
tar -xf swig-2.0.8.tar.gz
cd swig-2.0.8
./configure --prefix=$HOME
make
make install
Than get m2crypto,
svn checkout http://svn.osafoundation.org/m2crypto/tags/0.21/ m2crypto-0.21
cd m2crypto-0.21/
Edit fedora_setup.sh from this
SWIG_FEATURES=-cpperraswarn python setup.py $*
to this,
SWIG_FEATURES=-cpperraswarn python2.7 setup.py $*
Then build, then install,
./fedora_setup.sh build
./fedora_setup.sh install --prefix=$HOME
[me@web342 lib]$ python2.7

>>> import M2Crypto
>>> print M2Crypto
<module 'M2Crypto' from '/home/me/lib/python2.7/site-packages/M2Crypto-0.21-py2.7-linux-x86_64.egg/M2Crypto/__init__.pyc'>
Obviously, substitute your own details throughout. Hope this helps the next guy trying to install M2Crytpo using fedora_setup to a non-default python version.
