[scikit-image] Fw: Re: Compilation Problems

[Nathaniel Smith]

The easy way to check if your Python has SSL support is to do:
  python -c "import ssl"
and see if you get an error message.

If you do you then it's probably worth complaining to whoever installed
that Python so that they at least know that there's a problem -- this is a
pretty serious kind of brokenness, as you're discovering.

I agree with other posters that the quick/easy fix is to install Anaconda.

openssl-devel before building python.

How sure are you that this is causing my problem?  I
could build python and openssl-devel myself.  But
without root access, that could be a lot of work because
I'll have to track down each dependency manually.

Thank you for replying.
