Jinx requires the cterm package which provides an interface to curses. BSD-curses might not be good enough. Use ATT-curses if you have it. Cterm works fine on HP/UX, SunOs (if /usr/5bin/cc is used) and others. Ultrix has it's problems but should work. Jinx also requires plain Perl (PL18 and up).
Install cterm if you don't have it. See section 7 on how to get it. Unpack the Jinx stuff in a separate directory. If your Perl isn't in /local/bin/perl, change the first line in jinx, Jjoin, Jlist, Jproject, Jreport and Jsort to the proper #!-line.
Start Jinx by typing jinx. This may take some time. Jinx checks cterm to see if all the necessary curses functions and constants are defined in the cterm interface. If some required function is missing (or has a different name), look at the installation procedure for cterm on how to add a function to cterm. Leave Jinx with `q' if it starts up at all.
Study the Makefile. Edit the variables PERLLIB and BINDIR. They determine where the Perl libraries and programs go. Edit the variables LIBMODE and BINMODE. They determine the permissions of the installed Perl libraries and programs. Edit the names of the programs used in the Makefile if necessary.
If you have undump, make a binary version of Jinx with make dump.
Install Jinx with make dump-install if you are successful.
If you don't have undump, install Jinx with make install.
Install the manual page jinx.1 by hand.
If you have 
, do make doc and print jinx.dvi.
If not, pick up a PostScript version of the tutorial jinx.ps.
Read it and/or play.
