That seems a little odd to me.  Just checking, but take a look
at RT.pm.  Near the top, you should see something like this:

$SITE_CONFIG_FILE = "/usr/share/request-tracker3.4/etc/request-tracker3.4/RT_SiteConfig.pm";

$BasePath = '/usr/share/request-tracker3.4';

Later on, this code from the patch:

    if ($RT_INSTANCE_PATH) {
        foreach my $vref (@variables) {
            $$vref =~ s/^\Q$BasePath\E/$RT_INSTANCE_PATH/;
        }
    }

should turn $SITE_CONFIG_FILE into /home/testguy/etc/request-tracker3.4/RT_SiteConfig.pm

(I'm guessing at your directory structure, so this may not be exactly right for you.)

Yet your error message doesn't say anything about this file, it leaves
off the /home/testguy part.


If I were debugging this, I'd add some logging or print statements
to verify the changes in all the variables in the above loop,
and to verify that $RT_INSTANCE_PATH is set correctly,
since it seems to me, you are already in trouble by the time
you leave the RT::import() routine.
