alternative with index page
if ($oscTemplate->hasBlocks('boxes_column_right')) && ((basename($PHP_SELF) == FILENAME_DEFAULT)) {
?>
<div id="columnRight" class="grid_<?php echo $oscTemplate->getGridColumnWidth(); ?>">
<div><?php echo $oscTemplate->getBlocks('boxes_column_right'); ?></div> 

but it did not wo

You can do:

$basename = str_replace(".php","",basename($_SERVER['REQUEST_URI']));
if( $basename == "index" ) {
  //show right column
} 

OR

$name = basename($_SERVER['PHP_SELF']);
if ($oscTemplate->hasBlocks('boxes_column_right')) && (($name == "index.php")) {
  //show right column
}

did you mean something like that

I used this to do a similar task:

if ($current_page = FILENAME_DEFAULT) { //Show }
