You should note that if you distribute PrBoom then you must either
include the source code, or offer to provide source code on request, on
terms as described in section 3 of the license.

You don't have to distribute it unmodified. The license specifically
allows you to make & distribute modified versions, provided you offer
the source code for the modified work under the same license. And you
can leave out files that you don't need (much of the Boom & MBF docs,
for instance, are really for developers); only the license and copyright
files (COPYING and AUTHORS) must be included.

I am one of the authors of PrBoom. Certainly you are welcome to use
PrBoom - we are, in effect, the current version of Boom, so it is a
sensible choice - in accordance with the license terms.

I have assumed that your request is out of politeness, and you are not
asking for any formal legal permission. PrBoom is open-source, so you
don't need any extra permission from us to distribute it, or to
aggregate it with your own work, provided you are able to work within
the existing license terms. WAD files are 'independent and separate
works' in the terms of section 2 of the license (see the file
'copying'), so you can distribute your WAD file on your own terms and
distribute PrBoom alongside it. I imagine that the install program would
be interpreted as a separate work in the same way.
