Bugzilla Bug 115135

net-misc/tightvnc should block net-misc/vnc or the two should use different
names for their binaries, they both use /usr/bin/vncviewer. net-misc/vnc
currently blocks net-misc/tightvnc but net-misc/tightvnc does not block
net-misc/vnc.

Reproducible: Always
Steps to Reproduce:
1. emerge -C net-misc/tightvnc net-misc/vnc
2. emerge net-misc/tightvnc
3. emerge net-misc/vnc

Actual Results:  
net-misc/vnc and net-misc/tightvnc both break as a result of net-misc/vnc
replacing the binary for net-misc/tightvnc

Expected Results:  
net-misc/vnc should refuse to emerge if net-misc/tightvnc is installed.

Fixed in cvs, thanks!
net-misc/tightvnc already contains !net-misc/vnc, so I guess we're all good.
