Hi Monks

Sorry for asking again but am really stuck with this. I need to collect output of Perl modules installation. I am running on UNIX environment.
I am installing Perl modules (via Perl script) by using following command:
system (" perl -MCPAN -e 'install Bundle::Snapshot_2007_07_23_00' ")
The installation completed successfully.
In order to collect logs and see the output on the screen (because installation of some models is interactive) I did following changes:
system (" perl -MCPAN -e 'install Bundle::Snapshot_2007_07_23_00' | './1.pl' ")
when 1.pl is very simple:

while ($tmp = <STDIN> || $tmp = <STDERR>)
{
print $tmp;
write_to_log($tmp);
}

Now have 3 problems:
1. The interactive questions which were during installation are missing.
2. The program stuck during the modules installation.
3. The output is different from what I have before and some important parts are missing.

How I can solve those problems? Is there other way to collect Perl module installation logs?

Many thanks
