in thread perl install in Fedora 16

Not sure what you're expecting to happen when you say it didn't change.  Are you expecting to manipulate @INC permanently?  That's not how it works.  use lib ... changes @INC only for the lifetime of the script.  Also, use lib doesn't take a space-separated string of directories, but a list of directories, if you need more than one.

Consider this: 

#!/usr/bin/perl -wl
use strict;

BEGIN { print for @INC; print "-----" }
use lib "/usr/share/perl5/vendor_perl/AnyEvent/Iml", "/foo/bar";
BEGIN { print for @INC; print "-----" }

# use here whatever module lives in one of the added paths...

As you can see in the second printout of @INC (after the use lib), the two directories have been added.

P.S.:  please use <p>...</p> (text paragraph) and <c>...</c> (code) tags to format your posts.

For example, typing 

<p> inserting into the script: </p>
<c>
use lib "/usr/share/perl5/vendor_perl/AnyEvent/Iml";
</c>
<p> also does not change the entry. </p>

will render as

inserting into the script:

also does not change the entry.

    I added your code at the start of the script and the module was found! Now I have a new problem. The script (not mine) generates this error:

    Bareword "Tk::MainLoop" not allowed while "strict subs" in use at /usr
+/share/perl5/vendor_perl/AnyEvent/Impl/Tk.pm line 134.
Compilation failed in require at ./guiguts.pl line 49.
BEGIN failed--compilation aborted at ./guiguts.pl line 49.

    Line 49 is Tk.pm which is the module in the directory needed in @INC

      I'm not sure what you're actually trying to do, but from rereading the thread I'm getting the impression you might perhaps simply be wanting to run a regular Perl/Tk GUI program(?)

      If so, you need to install Tk, not AnyEvent::Impl::Tk.

      If, OTOH, you know what you're doing and are in fact wanting to use AnyEvent::Impl::Tk, you'll need to provide more context about what you're trying to run.  It's hard to help otherwise.

      As for the error message 'Bareword "Tk::MainLoop" not allowed ...' itself, it means something is trying to call said MainLoop function without having loaded the Tk module.

        I have been working in Project Gutenberg and the main tool they use for checking the text file is called "Guiguts". This is a perl program and is installed by running the script guiguts.pl. I have tried several times to install this program but have had the "Tk" issue. Tk.pm is installed on my comptuers (both a laptop and a desktop" and both generate the same errors, the modules are not installed where the rest of the *.pm files are located. If I copy them to the location where the other files are, the perl script will run but I get the other error about the MainLoop. After adding your script to the beginning of the guiguts script, perl finds Tk and the second error is generated about the MainLoop. If you want to inspect the script, the file is located here: http://sourceforge.net/project/showfiles.php?group_id=209389

        Thank you for your patience and help.
