It depends on what you modify,
And am not sure, if you are referring to modifying an addon, or the joomla stack
However, you are free to resell, but there are several hoops,
for example, there is a commercial joomla social distribution jomsocial, that
inherits the joomla core
For drupal, they are some commercial distro's and this practice is the norm
The only issue is acknowledged works, you cant use the source code, modify it,
and claim it
Its a bit complex and simple, depending on what u want to do
the devil is in the details

Hi Tim,
Thanks for the insight. I'm not planning on making money from turning an
open source library to closed source, but I don't want to be under the
obligation to open source software because I included a library in it.
I really wonder how that works, because for example joomla is under GPL v2,
so if I create a website based on joomla, modify some parts of joomla, do I
have to open source it?
But I guess I can keep my mind open on open source business models.
Daniel.

Hi Daniel,
You can use any software that is released under a permissive license:
http://en.wikipedia.org/wiki/Permissive_free_software_licence
However I would say, as an accountant and a business man who has sat on the
board of the many companies over the years, that turning open source
software into proprietary software is bad business practice.
That is unless you have the marketing budget of Apple inc. and you don't.
If you are planning on trying to make money from your software then you are
much better keeping it open.
I remember reading a quote (I can't seem to lay my hands on it now) by Bob
Young (one of the founders of Red Hat a billion dollar a year Free software
company) that when he first read the GPL, where others saw socialism he saw
a great business model. There is an interesting paper from him here:
http://quod.lib.umich.edu/cgi/t/text/text-idx?c=jep;view=text;rgn=main;idno=
3336451.0004.304
Making money from Free software just requires you throw away the usual
preconceptions of business, and use your imagination instead.
Thanks
Tim
