[Nix-dev] How to build PHP with xdebug support

[Paul Koerbitz]

So I have found a workaround just after posting to this list: I am now
using a php.ini file from my home directory and have $PHPRC set to
this ini file. I've simply hardcoded the paths to xdebug in this
php.ini file.

This workaround works for me know, but I'm still interested if there
is a more elegant solution.

cheers
Paul
