PorterDir does not work properly

[jcn]

In my configuration at least (Ubuntu 9.04, Apache installed through apt-get, apreq installed from source as described in the docs), PorterDir doesn't change the location of the uploaded files. The problem is in the following section:

http://github.com/actionrails/modporter/blob/master/mod_porter.c#L354-367

In my case, the upload brigade has a spool file, meaning that the section that would actually set the path is never getting called.

I was thinking that apreq_temp_dir_set could be set somewhere earlier when the request reference is fetched, but that doesn't seem to work. Any insights into this would be great. Thanks!
