Please test this package against PHP 5.0.1.
If the package works, please add a comment to this bug to say that the package works, and close this bug as 'RESOLVED INVALID'.
If the package does not work, please add a blocker against 'virtual/php' (for dev-php/php) or 'virtual/httpd-php' (for mod_php or php-cgi) as appropriate, and close this bug as 'RESOLVED FIXED'.
I don't know if zuul will work in php5 but currently zuul won't work with any current release of mldonkey anyway.
The upstream devs recommend masking this package if possible until they release 2.0.
No time to test, but there is a Zuul fork: http://web-gmui.sourceforge.net/
Marking WONTFIX wrt Bug 74985.
