If you look at the layout update file for the module most likely there will be a section that is defining the block as a child of another. If that is the case then you can implement the same logic for the product page layout and call it there with getChildHtml('block_name').
Take a sample from the catalog.xml of the base/default magento theme.
In this node:
<catalog_product_view translate="label"> you will find
<reference name="content"> and in there you will find the
<block type="catalog/product_view_media" name="product.info.media" as="media" template="catalog/product/view/media.phtml"/> declaration. If you now go to
catalog/product/view.phtml you will see something like
<?php echo $this->getChildHtml('media') ?>.
By the same method you can define the recently viewed products to be used on the product display page.
Most likely you will need to format the display but it should get you in the right direction.
If it currently displays other places, then in that layout xml you can remove the definitions or in the templates that it is called from you can remove the calls.
Hope this helps.
