net/pvm: slightly misleading message

[Poul-Henning Kamp]

ports/net/pvm spits out some helpfull advice which is marred by the
fact that it is slightly misleading.  Notice the two different paths:

-----
You have to set PVM_ROOT=/usr/local/lib/pvm enviropment variable on all machines
which you are planning to use for distributed computing. The best way to set
this variable on system-wide basis is to add "PVM_ROOT=/opt/lib/pvm" into
appropriate section of your /etc/login.conf file. You also have to enable
rshd on those machines.
