Note that the Windows binaries already contain xlwt and xlrd. Jürgen
was so kind to include it, because I needed it as well for my
plugins. Not sure about openpyxl. On Linux systems it is rather easy
to install them through apt-get, pip or similar mechanisms. Just
tell your users that/how they need/can install them.<span><font color="#888888"><br>

We are currently developing a QGIS plugin were
we wish to generate some Excel files as output. <br>
<br>
In order to build the spreadsheet file we need
to use some python modules installed from pip
(openpyxl, xlwt, etc). This dependency will
force every user to manually install the needed
package form the pip repository.<br>
<br>
</div>
This situation leaves us with the following
question: is possible or it will be in the future
to manage this kind of dependencies from QGIS side
when the user installs the plugin? <br>

<div>Although it has been discussed and some prototyping was
done to support automatic installation of dependencies at
the last hackfest, there isn’t anything in the released
versions of QGIS to support this yet. If your packages
have no operating system specific binaries in them, then I
suggest to bundle them into your plugin and use an
appropriate import path relative to your code. Note there
is a limit on how big your plugin can be (I think it is
10mb) so you need to ensure your 3rd party deps do not
bulk out your plugin too much.</div>

We bundled xlwt and xlrd as .egg with a plugin recently:<br>
<br>
<a href="https://github.com/opengisch/shpsync/blob/master/xlwt-1.0.0-py2.7.egg" target="_blank">https://github.com/opengisch/shpsync/blob/master/xlwt-1.0.0-py2.7.egg</a><br>
<a href="https://github.com/opengisch/shpsync/blob/master/xlrd-0.9.4-py2.7.egg" target="_blank">https://github.com/opengisch/shpsync/blob/master/xlrd-0.9.4-py2.7.egg</a><br>
<br>
Until there's a cross-platform dependency management (which I know
that several people are looking into) that's the safest road to
follow.<br>
