Handling "Didn't find any processor named: p16f1454"

If you try to compile the PIC16F1-USB-DFU-Bootloader source code and get the following error:

Didn't find any processor named: p16f1454

You've been saddled with an antique version of gputils. For some reason, the packages in Linux distributions have not kept pace with newer versions (i.e. gpasm-0.13.7 being distributed versus gpasm-1.5.0 being the latest at the time of writing).

The gputils project's main page is here:

http://gputils.sourceforge.net/

and what follows is a cheatsheet that might help you compile and install the latest version:

sudo apt-get install subversion bison flex gcc build-essential
svn checkout svn://svn.code.sf.net/p/gputils/code/trunk .
cd gputils
./configure
make
sudo make install
