Hi all,

I'm trying to build the geometry stack on osx Lion bu I got the following error during the building of Eigen:

mkdir -p build
if [ ! -f eigen-3.0prebeta3.tar.bz2.md5sum ]; then echo "Error: Couldn't find md5sum file eigen-3.0prebeta3.tar.bz2.md5sum" && false; fi

    raise IOError, ('url error', 'unknown url type', type)
IOError: [Errno url error] unknown url type: 'https'
make: *** [build/eigen/unpacked] Error 1

Do you know how I can fix it? I read somewhere that I should switch to urllib2 but I don't know how to do it.

Thanks

I found a better solution:

cd /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/
sudo cp /System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/_ssl.so .

I don't know way bu it seems that the _ssl.do module is not installed through macport.

From this stack overflow question axaroth's comment looks applicable. You need to recompile Python with OpenSSL installed/enabled.

So, `sudo port -f uninstall python26` -> `sudo port install openssl` -> `sudo port install python26`. I already tried it and it unlikely it doesn't work...

Luca, you probably need to install python26 with the openssl variant: `sudo port install python26 +openssl`. Let me know if that works. I am going to test this build with the built-in python.

@William It seems that the `openssl` variant is not available: http://www.macports.org/ports.php?by=library&substr=python26 . Anyway, I found a workaround. Look at my answer. Of course it is not the best way.

@LucaGhera Ah, I was looking at the dependencies, I feel silly, I will keep looking for an alternative.

@William I posted a better solution.
