An update From Sébastien in Issue 85 regarding installing specific versions
of packages, i.e. pydicom:

The currently installed version of pydicom can be obtained through 2
equivalent commands:

{{{`# pip search pydicom`

`# python -c "import dicom; print dicom.__version__"`}}}

To force pydicom 0.9.8 to be installed, type:

{{{`# sudo pip install pydicom==0.9.8`}}}

Thanks for the guide.

Here is a recent experience with dicompyler 0.4.2 (as of January 2015) on
Ubuntu 14.04:
I first attempted to install it via
code{$ sudo apt-get install dicompyler}
However, when I called it from terminal, I received
code{user@machine$ dicompyler
/usr/bin/python: No module named main}

I then uninstalled the dicompyler by running
code{$ sudo apt-get remove --purge dicompyler}

After that I checked whether the
[https://code.google.com/p/dicompyler/wiki/BuildRequirements dicompyler
package dependencies] are satisfied by displaying installed package
versions using
code{$ pip show <package name>} for each of the listed packages.

It has turned out that pydicom and matplotlib installed on my system were
too recent. I uninstalled these packages and replaced them by older
versions compatible with dicompyler
by running
code{$ sudo pip install matplotlib==1.1.0}
and
code{$ sudo pip install pydicom==0.9.6
https://code.google.com/p/pydicom/downloads/detail?name=pydicom-0.9.6.tar.gz}

After all dependencies were satisfied, I have downloaded and extracted
dicompyler
[https://pypi.python.org/packages/source/d/dicompyler/dicompyler-0.4.2.tar.gz#md5=adbfa47b07f983f17fdba26a1442fce0
source tarball]
into the folder /home/myuser/dicompyler

I then attempted to install dicompyler by
code{sudo pip install dicompyler /home/myuser/dicompyler}

This resulted in error messages

Thank you for the update and helpful information! Many dependencies have
been updated since the previous release of dicompyler, and I did not get a
chance to test with Ubuntu.

Comment by homman...@gmail.com:

A small note: dicompyler 0.4.2 requires wxPython to be installed. This
dependency is not downloaded when dicompyler is installed. Installing
python-wxgtk2.8 pre- or post-dicompyler installation fixes the issue.
