[... other indentation mistakes ...]

Oh, for the love of God, if you want other people to look at your code
then please make it readable. That *includes* "having proper
indentation". Having to look at such messy code just made my eyes bleed.

That being said,

directly using values which you extract using a regex like that has
issues with glib (it wants to have modifiable variables, which these
things aren't). Try assigning them to temporary variables before going
on:

if($line =~ /(\d*\.?\d*)(.*)/) {
        my $fraction=$1;
        my $text=$2;
        $pbar->set_fraction($fraction);
        $pbar->set_text($text);
}

Also, I don't think fractional values are allowed for a progress bar.
