errors in Linux

[Pietro Terna]

I have Linux Binary Distribution of Swarm 1.0.0 installed in my box.
All apps and tutorials seem to work, but running them I receive several
error messages, as those reported below.

Is this a consequence of errors in library settings in my box? I'm using
Linux 2.0.29 with XFree86 3.2

Many thanks for help, Pietro
