Problem displaying Solr search results running php as cgi

I'm running an older version of this module, but considering the issue, I don't believe a newer version would affect things.

I'm running a site on a VPS which by default runs php as an apache module, but in order to allow proper file permissions and access to php.ini we must run php as a cgi binary and use php-cgiwrap. When running as an apache module everything works fine.

We had to add the following to our otherwise default drupal .htaccess file.

  Action application/x-pair-sphp5 /cgi-sys/php-cgiwrap/VPS_UserName/php5.cgi
  AddType application/x-pair-sphp5 .php

On Solr search results pages we now get Internal Server Error 500.

Here's a snippet from the error log

malformed header from script. Bad header=Array: php-cgiwrap

I also tried editing php.ini and .htaccess with information the VPS provides on Using PHP - PHP File Access, but the result was the same. (commented out allow_url_fopen in php.ini and added php_flag allow_url_fopen on to .htaccess)

Any help would be greatly appreciated.
