You can do the normal -d debug under mod_perl, see:
http://perl.apache.org/guide/debug.html
BTW, has anyone came with a solution for ptkdb to work more than once
under mod_perl? The author has never replied to my inqueries :(

package Foo;
use constant DEBUG => 1;
...
warn "foo" if DEBUG;
...
package Bar;
use constant DEBUG => 0;
...
warn "bar" if DEBUG;
...
you get the idea... Only warns in Foo will work...
you can keep the debug statements in the code without having any overhead
of doing if DEBUG, since they are stripped at compile time.
