Par-port access - via ver. 1.0.2 ? readlink

[easlab@absamail.co.za]

My hope was to be able to drive this DOS-application without
re-booting to DOS. It uses the parallel-port.

dosemu-1.0.2-bin.tgz runs dos-applications but I can't toggle 
port hex378, nor after setting  *.conf.

Being advised to use ver. 1.1.99.1, I try to install as non-root,
unpacking  freedos before dos-emu [extra problems to chown, chgrp,
and set permissions for the 2 *.tgz since they were fetched by root].

Run attempt for ./dosemu   gives clear error messages: --------
 Creating symbolic link for bootdirectory as /root/.dosemu/drives/c  <-- OK

./dosemu: readlink: command not found     <--? no such 'executable' ?
./dosemu: /../bin/dosemu.bin: No such file or directory
exec: /../bin/dosemu.bin: cannot execute: No such file or directory
------------

The  dosemu  bash-script reads:-----------
...
if [ -z "$IS_SYSTEM_WIDE" ]; then
  BOOT_DIR_PATH=`readlink $HOME/.dosemu/drives/c`/..    <----- ??
fi
---------
I was hoping not to have to do course on bash to run my application,
but it seems to me that "readlink" is expected to be a command
[with 2 arguments]. 

I have no such executable on my RH 6.2 installation.

Please advuse me how I should proceed.
