I'm not using nginx/cgiwrap-fcgi.pl, but for fastcgi process 
management I doubt it matters which http server is being used. I 
suggest (& use) daemontools.

http://cr.yp.to/daemontools.html

The run script can be as simple as:

-----------------------------------
#!/bin/sh

exec 2>&1
exec setuidgid appuser envdir ./env 
/home/appuser/myapp/script/myapp_fastcgi.pl -e -l 127.0.0.1:3010
-----------------------------------


The env dir can contain files to populate environment variable, eg:

$ cat /service/catalyst-appuser/env/PERL5LIB
/home/appuser/lib/perl5/

$ cat /service/catalyst-appuser/env/CATALYST_DEBUG
0


We were already using daemontools for a number of other 
services, so adding catalyst process management was simple.
