problem starting radiusd with perl module

[maury]

Hi
I have problem to start radiusd with perl module authentication support.
.....
Module: Instantiated exec (exec)
Module: Loaded expr
Module: Instantiated expr (expr)
Module: Loaded perl
perl: module = "/etc/raddb/example.pl"
perl: func_authorize = "authorize"
perl: func_authenticate = "authenticate"
perl: func_accounting = "accounting"
perl: func_preacct = "preacct"
perl: func_checksimul = "checksimul"
perl: func_detach = "detach"
perl: func_xlat = "xlat"
perl: func_pre_proxy = "pre_proxy"
perl: func_post_proxy = "post_proxy"
perl: func_post_auth = "post_auth"
perl: perl_flags = "(null)"
perl: func_start_accounting = "(null)"
perl: func_stop_accounting = "(null)"
Segmentation fault

I have installed freeradius 1.1.0 stable on redhat es 3 and  I have 
compiled with
this options:
./configure \
       --with-logdir=/var/log/radius \
       --with-raddbdir=/etc/raddb \
       --disable-static \
       --enable-shared \
       --enable-ucd-snmp-compatibility \
       --with-gnu-ld \
       --with-threads \
       --with-thread-pool \
       --disable-ltdl-install \
       --with-rlm-sql_mysql-include-dir=/usr/include/mysql \
       --with-rlm-krb5-include-dir=/usr/kerberos/include
I have configurate radiusd.conf

modules {
.....
....
....
$INCLUDE ${confdir}/experimental.conf
}


authenticate {
....
....
...
   perl
.......
}

Any idea o suggest?
Thank you
