yum fails with pycurl version error

[Alex Regan]

Hi,
A recent fedora20 update broke yum:

# yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

    pycurl: libcurl link-time version (7.29.0) is older than 
compile-time version (7.32.0)

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.5 (default, Nov  3 2014, 14:26:24)
[GCC 4.8.3 20140911 (Red Hat 4.8.3-7)]

If you cannot solve this problem yourself, please go to
the yum faq at:
   http://yum.baseurl.org/wiki/Faq

Any ideas what caused this or how to fix it?

Thanks,
Alex
