Cannot start xampp -- 32 bit compatability error

Question

just installed xampp for the first time.  i used the latest version (1.8.1-1) from the AUR.
trying to start it by running:
sudo xampp start
gives the following error:
XAMPP is currently only availably as 32 bit application. Please use a 32 bit compatibility library for your system.
i am running a 64 bit system, but i have installed gcc-libs-multilib-4.8.0-4, lib32-gcc-libs-4.8.0-4, and gcc-multilib-4.8.0-4
the relevant section from /opt/bin/lampp (which /usr/bin/xampp is a symlink to):
# XAMPP is currently 32 bit only
case `uname -m` in
*_64)
if /opt/lampp/bin/php -v > /dev/null 2>&1
then
else
$de && echo "XAMPP gibt es zur Zeit nur als 32-Bit Applikation. Bitte verwende eine 32-Bit Kompatibilitaetsbibliothek fuer Dein System."
$de || echo "XAMPP is currently only availably as 32 bit application. Please use a 32 bit compatibility library for your system."
exit
fi
esac
trying to run
sudo /opt/lampp/bin/php
returns
bash: /opt/lampp/bin/php: Permission denied
the relevant permissions are:
lrwxrwxrwx 1 root root 9 Sep 19 2012 /opt/lampp/bin/php -> php-5.4.7
-rwxr-xr-x 1 root root 9.8M Sep 30 2012 /opt/lampp/bin/php-5.4.7
any ideas?
