Download the Micropolis source (micropolis-activity-source.tgz) from http://www.donhopkins.com/home/micropolis/.
Install the following packages:
sudo apt-get install libx11-dev libxpm-dev x11proto-xext-dev libxext-dev
Micropolis requires yacc to compile properly. Bison is the recommended replacement package for yacc however errors were generated and Micropolis would not compile. I used the FreeBSD package freebsd5-buildutils instead:
sudo apt-get install freebsd5-buildutils
