crossfire metaserver2 notification error

[reini]

When I turn on metaserver2 notification in /etc/crossfire/metaserver2, I get the following error in the logs:

========================

12/01/23 09:37:57 [Error] metaserver2 file is set to do notification, but libcurl is not found.

libcurl3 is installed, but apparently not found at compile-time.
