Drupal 6 replaces the views_build_view by views_embed_view, which make sense at least by the name of function.
$viewName = 'MYVIEWNAME'; print views_embed_view($viewName);
The views_embed_view has 2 default arguments. The second argument allows you to enter the display_id of the view (example: default, page, block, etc). Any additional argument you specify will be passed to the views argument handler. For instance, if you wanted to embed the block view and pass it a list of nodeIDs as an argument.
$viewName = 'MYVIEWNAME'; $display_id = 'block'; $myNodes = array(1, 2, 3); print views_embed_view($viewName, $display_id, $myNodes);
