That's interesting; Parse::RecDescent does indeed use $&.

The problem is not that it won't run in mod_perl, that problem is that using $& can slow down Perl scripts. More specifically, using $& (or its friends) anywhere in a Perl script will cause all regexps with no captures to run slower than normal. In mod_perl, this would apply to all scripts running in a given mod_perl process.
