Failed to re-build pycurl with OpenSSL

Question

I'm trying to rebuild pycurl with OpenSSL because of this bug. I use this example:

1. sudo apt-get install build-essential fakeroot dpkg-dev
2. mkdir ~/python-pycurl-openssl
3. cd ~/python-pycurl-openssl
4. sudo apt-get source python-pycurl
5. sudo apt-get build-dep python-pycurl
6. sudo apt-get install libcurl4-openssl-dev
7. sudo dpkg-source -x pycurl_7.19.3-0ubuntu3.dsc
8. cd pycurl-7.19.3
9. edit debian/control file and replace all instances of 'libcurl4-gnutls-dev' with 'libcurl4-openssl-dev' (7 changes)
10. sudo PYCURL_SSL_LIBRARY=openssl dpkg-buildpackage -rfakeroot -b
11. sudo dpkg -i ../python-pycurl_7.19.3-0ubuntu3_amd64.deb

But after all I'm still stuck with GnuTLS build of pycurl.

>>> pycurl.version
'PycURL/7.19.5.1 libcurl/7.35.0 GnuTLS/2.12.23 zlib/1.2.8 libidn/1.28 librtmp/2.3'

Operation log (there are some error's tracebacks): http://pastebin.com/6hUEUGar

I use:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:    14.04
Codename:   trusty

What am I doing wrong?

I could solve the problem using pip:

sudo pip uninstall pycurl
export PYCURL_SSL_LIBRARY=openssl
sudo pip install pycurl --upgrade

Now:

>>> pycurl.version
'PycURL/7.19.5.1 libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3'

But I'm not sure It's right. Why are there two package in the system? Or it's ok and python is just linked to one of them?
