Still no.

If you are running perl as a CGI script, it creates a separate process each 
time, which allows that script to be run as a different user. If you are 
running mod_perl, the perl interpreter is embedded in the apache process and 
thus runs as whatever user apache is running as.

If you need both mod_perl and your perl to run as different users you'd have 
to run one instance of apache per user, as that user, and a reverse proxy to 
farm off the requests to the appropriate server.
