[Techtalk] Help, I'm confused

[pmurphre at indiana.edu]

Hi,

OK, I'm attempting to install Corel's WordPerfect for Linux.  In the
readme file for the installation, the following statement appears,
following instructions to unzip and untar the appropriate files, which
I have managed to do--

"Note: In order for the GUI interface to work, your display
environment must be set correctly."

Then, the ever so helpful document states

"The Runme script must operate within the /bin/sh environment"

Am I correct in assuming that these two items are related?  If so,
what does this indicate that I should do on the command line?  I ask
because I have probably spent at least 8 hours trying various
solutions, only to inevitably end up with a situation where the Runme
script will activate and then be unable to locate any of the files
necessary to perform the installation.  As I have untarred and
unzipped the files and placed them in a directory (as instructed by
the ever-so-helpful (heavy sarcasm) installation guide), I can't
understand why the Runme script cannot seem to locate them.  

I don't think I am a stupid person, but I am starting to have grave
doubts about my decision to switch to Linux, since I can't even manage
to install a simple program.  Any help would be greatly appreciated. 
Thank you.

Sincerely,
Murph
