20040419: 20040419: GEMPAK installation help

Andrew,

Inter process communication (or IPC) and message queues are
one way in which programs can communicate between themselves.
MAC OSX does not support this. With the ipc.h and msg.h
include files. the programs will link because the stubs are
in the C library in netbsd. However, when a program asks for
a message queue, none will be created. See:
http://www.unidata.ucar.edu/projects/coohl/mhonarc/MailArchives/gempak/msg05909.html
This is because while netBSD supports the API, the underlying
Darwin operating system does not, eg, the routines just return -1 without doing 
anything..

The GEMPAK programs (any that talk to a device driver or gplt)
use message queues to do mapping transformations and display.
The GUIs have the gplt and xw/ps/gif drivers all linked into a single 
executable,
so they do not communicate among separate programs....they will work, as will
decoders.
