[xdebug-general] installing xdebug-2.1.3

Trying to run inside the directory "xdebug-2.1.3" the command:
sudo /opt/lampp/bin/phpize-5.3.8
for lampp 1.7.7

I got the error message:
Cannot find config.m4.
Make sure that you run '/opt/lampp/bin/phpize-5.3.8' in the top level
source directory of the module

I thought I had done the very same thing when installing xdebug on lampp
1.7.2 but maybe not.

Any ideas on why phpize can't find config.m4?
Thanks for any help.
