[mod_python] Trouble compiling mod_python on gentoo

Hi all

I am unable to compile mod_python on a gentoo machine (all updated,
~x86, etc), both using emerge and by hand, please help if you can... 
(Also, please email me directly as well as the list, if possible).

Here is my configure command:

./configure --prefix=/usr/local/mod_python-3.1.4  --with-apxs=/usr/sbin/apxs2

Here is the error:

<snip>
checking where Python include files are... -I/usr/include/python2.4
./configure: line 2951: syntax error near unexpected token `('
./configure: line 2951: `as_me=`(basename "$0") 2>/dev/null ||'

Here are my specs:

mod_python version: 3.1.4, but same error on 3.2.5b and 3.1.3
bash version: 3.1.5
apache2 -V:
Server version: Apache/2.0.55
Server built:   Jan 12 2006 03:53:14
Server's Module Magic Number: 20020903:11
Architecture:   32-bit
Server compiled with....
 -D APACHE_MPM_DIR="server/mpm/prefork"
 -D APR_HAS_SENDFILE
 -D APR_HAS_MMAP
 -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
 -D APR_USE_SYSVSEM_SERIALIZE
 -D APR_USE_PTHREAD_SERIALIZE
 -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
 -D APR_HAS_OTHER_CHILD
 -D AP_HAVE_RELIABLE_PIPED_LOGS
 -D HTTPD_ROOT="/usr"
 -D SUEXEC_BIN="/usr/sbin/suexec2"
 -D DEFAULT_PIDLOG="/var/run/httpd.pid"
 -D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
 -D DEFAULT_LOCKFILE="/var/run/accept.lock"
 -D DEFAULT_ERRORLOG="logs/error_log"
 -D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types"
 -D SERVER_CONFIG_FILE="/etc/apache2/httpd.conf"

Here is where I think the configure script goes south:

# Name of the executable.
as_me=`(basename "$0") 2>/dev/null ||                   ## This is line 2951
$as_expr X/"$0" : '.*/\([^/][^/]*\)/*$' \| \
         X"$0" : 'X\(//\)$' \| \
         X"$0" : 'X\(/\)$' \| \
         .     : '\(.\)' 2>/dev/null ||
echo X/"$0" |
    sed '/^.*\/\([^/][^/]*\)\/*$/{ s//\1/; q; }
          /^X\/\(\/\/\)$/{ s//\1/; q; }
          /^X\/\(\/\).*/{ s//\1/; q; }
          s/.*/./; q'`

Any help would be great, or I can file a bug report if someone tells me where.

Thx
