Python Conda install old version of matplotlib keyerror linux3

While trying to install the tool PrimerProspector from the development version (SVN trunk, as instructed here: http://pprospector.sourceforge.net/install/install.html) I tried creating a conda environment to resolve the dependencies in an elegant way (I am running an Ubuntu server 16.04.3 LTS machine with conda 4.4.8). The PyCogent and Numpy can easily be installed in the required version using pip install when the environment (with python 2.6) is activated. I have conda forge in my channels. However, when running pip install matplotlib==0.98.5.3 I run into the issue that there is no such version available (Could not find a version that satisfies the requirement matplotlib==0.98.5.3 (from versions: 0.86, 0.86.1, 0.86.2, 0.91.0, 0.91.1, 1.0.1, 1.1.0, 1.1.1, 1.2.0, 1.2.1, 1.3.0, 1.3.1, 1.4.0, 1.4.1rc1, 1.4.1, 1.4.2, 1.4.3, 1.5.0, 1.5.1, 1.5.2, 1.5.3, 2.0.0b1, 2.0.0b2, 2.0.0b3, 2.0.0b4, 2.0.0rc1, 2.0.0rc2, 2.0.0, 2.0.1, 2.0.2, 2.1.0rc1, 2.1.0, 2.1.1, 2.1.2)). Additionally I get an InsecurePlatformWarning which is apparently common with an older Python distribution. Nevertheless, as the source was available I tried using pip to install from the tarball. This gives me the rather uninformative KeyError: 'linux3':

Complete output from command python setup.py egg_info:
    ============================================================================

        [os.path.join(p, 'include') for p in basedir[sys.platform] ])
    KeyError: 'linux3'

    ----------------------------------------

Directly running setup.py after untarring also renders the same error. Does anyone know how to resolve this? Is there anything I can do to find out?

The mathplotlib version you're trying to use has been released years before the release of Linux 3.0. That's why it has no support for sys.platform='linux3'. And the Python version you're using is older than 2.7.2, which dropped setting the linux3 value.

You can try to just edit the setupext.py file in the tarball, and in the dict basedir add config for linux3, which would be the same as for linux and linux2.
