The xchat-2.0.1 Ebuild contained a line in src_install() to link the binary
xchat-2 to xchat if no other version of xchat was installed, see bug #19441. I
still think this is a good idea, and I'd be happy if that change could make it
into the 2.0.2 and 2.0.3 ebuilds as well. Thanks...
I removed it as unneeded and it being a bad habit that 2 different packages (slots) can share the same physical files. Note that this change back then was made without my knowledge or consent.
