KNOWN BUGS AND WORKAROUNDS

Silicon Graphics:

	The network lock manager is a bit flakey, and may require
	some repair to work with version 5.x of IRIX.  Without a
	working lock manager, rpict, rtrace and rview will not be able
	to share ambient files while running simultaneously.  Also,
	rpiece will not work.

	Make sure that the NFS lock daemon is running (run
	/etc/chkconfig | grep lockd).  If it isn't, run "/etc/chkconfig
	lockd on" as root and reboot.

System V derivative UNIX's (including LINUX):

	The network lock manager in general seems to be unreliable on
	some UNIX implementations, so rpiece may abort with strange results.
	Please take the time to complain to your vendor if you
	run into this problem.  It's going to take a lot of people
	coming to them before they're likely to do anything about it.

	If the renderers give you some message about not being able
	to lock or unlock a file, you can add the following line
	to the end of src/common/standard.h as a last resort:

	#undef F_SETLKW

	You should definitely do this if you are running LINUX --
	I know for sure that the ambient files are corrupted otherwise
	on this system.  The above should remove all the dependent code,
	killing rpiece in the process.

	Some Linux's (1.2.3) seem to have a peculiar problem with their
	C-shell that causes it to add extra spaces at the end of each
	line in the rmake script.  It may be necessary to go in and
	delete these spaces if the makeall sequence fails to produce
	anything.


DEC Alpha Workstations

	The global ucode optimizer doesn't seem to like the use of global
	variables in ray/src/rt/noise3.c, so it is necessary to compile
	this module separately with -O1.  I wish there were some automatic
	way to do this, but I can't think of one.  Until they fix this
	compiler bug, it is necessary to manually go into the src/rt
	directory and execute the following (after running makeall install):

	% rm noise3.o
	% rmake -n noise3.o
	% # copy above line, but change -O to -O1
	% rmake install

	Some Alpha's seem to have a peculiar problem with their
	C-shell that causes it to add extra spaces at the end of each
	line in the rmake script.  It may be necessary to go in and
	delete these spaces if the makeall sequence fails to produce
	anything.

	I have also noticed that the compiler barfs on src/px/cut.c
	for no good reason, causing the installation to fail.  It
	is necessary to remove the ra_pr command from the PROGS
	list to get "rmake install" to work in that directory.  Drat!
