I believe the head version of public/.htaccess has a bug causing the dispatch.cgi to have precedence over dispatch.fcgi
when both modules are installed because of the order of the RewriteRule directives.

<IfModule mod_fastcgi.c>
    RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>
<IfModule mod_fcgid.c>
    RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>
<IfModule mod_cgi.c>
    RewriteRule ^(.*)$ dispatch.cgi [QSA,L]
</IfModule>

This will always cause the URL to be rewritten to dispatch.cgi whenever mod_cgi is installed. I assume that you would
likely want fcgi over cgi when available, so the cgi rewrite should move to the top of the list, as in:

<IfModule mod_cgi.c>
    RewriteRule ^(.*)$ dispatch.cgi [QSA,L]
</IfModule>
<IfModule mod_fastcgi.c>
    RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>
<IfModule mod_fcgid.c>
    RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>

I'm not sure if fastcgi or fcgid would be more preferred, but that order can also easily change.
