-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all,
The other point for compilation is stability. I have something weird on my system that causes kde to crash VERY regulary, if I compile my own set, this goes away. As for compiling it can be as simple as issuing the command apt-get source --compile <package name> Regards, Stephen.
