To recap, I managed to install the development tools, download the source
code and add a -DSIMULATED_MOTORS to the RTFLAGS line in src/Makefile.inc.
So last night, I did the following from /src as root:

./configure
Make 
Sudo make modules_install

(hopefully this is what you meant when you said to run make
modules_install)!

Everything recompiled at this point and it appeared to complete
successfully.  When I launched generic.run however, I still had the same
problem with the x-axis display freezing when I manually spun the motor
shaft.

So as an experiment, I increased the max acceleration and velocity values in
the generic.ini file to 100000 and that seems to have solved the problem.  I
felt like an idiot for not trying that before recompiling everything but at
least I now know how.  Thanks again for the help Paul.
